Verizon Changing Users Router Passwords

Maybe they were able to access your router because the password was still password1 ?

[phoenixwade]

I thought that blocking administrative access from WAN would have been enough.

I'm gonna get modded troll for this, but "Thinking" was not what you were doing.

You missed thinking in three key ways:

• you didn't change the default password to something other than a common default password
• You apparently were upset by them doing you a favor and changing the password
• And the least amount of thinking in this entire thing: You told the Slashdot community about this? you deserve every thing you are about to read.

>>>A UK citizen...threatened with exportation & 20 years imprisonment by the current administration.

Also this is a clear indication of a double standard and Inequality under the law. If a government or corporation leaves the password as 'password1' and a citizen enters that computer, then the citizen will be severely punished. BUT in the opposite case of government/corporation entering a citizen's private computer or router?

That's okay.

Re:uhhh

[Ksevio]

No, they were able to because they used their backdoor which has it's own password to login and change it.

Realistically the password of the router doesn't matter if you have remote management turned off, but Verizon thinks that people are going around cracking the WEP keys and changing peoples routers.

They did the same to my router so I blocked port 4567.

Re:uhhh

[complacence]

What are you all on about? He said he disabled administrative access from outside. No matter the password, there's intrusion going on here, so there is something to talk about.

If a password was all there is to protect your router from outside, all hell would break loose for simple brute forcing. You also can't expect Aunt Irma to change her password first thing when she gets net access.

Finally, even disregarding all that, even if he was stupid and careless, they can't just access the router if he didn't explicitly give them the right in a contract somewhere. I get you're all supercomputerexperts, but maybe we could talk about what he's asking?

Why is there an open forced access port/back door?
Is that ok without telling the owner?
What security is in place that entities besides Verizon can't access it?

Re:uhhh

[gparent]

If they can access the router when administrative access is disabled, what makes you think they cannot bypass the password system anyway?

Re:uhhh

[harlows_monkeys]

A UK citizen who used a similar backdoor (typed the default password) to get into a US computer is now being raked-over-the-coals and threatened with exportation & 20 years imprisonment by the current administration. If it wasn't okay for him to enter a privately-owned computer, why it is okay for Verizon to enter a privately-owned router?

Did Verizon leave threatening messages promising continued disruption? Did Verizon attempt to conceal their activity by deleting log files? Was Verizon attempting to gain access to the user's private data?

The answer to all of these is "no", making this totally different from the McKinnon case. (And these are just the things McKinnon admits to. He's alleged to have been much more destructive).

Also, the router is connected to Verizon's network, and was set up by Verizon for the customer. Even if the customer owns the router, it is is quite likely there is a contract between the customer and Verizon allowing them to access it for administrative purposes. Did McKinnon have a contract with the owners of the 96 or so computers he hacked? Were they on a network he owned and using a service he provided?

Re:uhhh

[Ksevio]

If that were the whole story then it would be end of thread. Verizon changed the LAN side password remotely using their backdoor to the system. The backdoor uses a completely different authentication system. The only time the LAN side access password is useful is if you're already on the network, at which point there are probably more pressing security issues.

Re:uhhh

[mystik]

If you read the ToS (for VZ Fios, Even Cox Cable has a similar provision) by agreeing to service, you authorize them to access your equipment.

Re:uhhh

[Jah-Wren Ryel]

I have fios and I have gone to my own software router running in a VM. But before I completely dumped the actiontec (which is really nice hardware for a router, but not all the well supported by alternative firmwares due to actiontec being asses about the GPL for a really long time), I noticed traffic on that port. After only cursory investigation, the impression I got was that the router was "phoning home" to verizon. That's how it got firmware updates and, I presume in this case, the password was changed. That "phoning home" behavior was something that creeped me out because I have no idea what it's reporting or what changes might be made, so it's what goosed me to start looking into alternative firmwares and eventually go the VM route instead.

Re:uhhh

[Anonymous Coward]

If his FIOS router is something like the Actiontec MI424WR, the datasheet specifically states it supports TR-069

Its their CPE, not his router, even if he changed the passwords and changed the firewall.

Re:uhhh

[Roger W Moore]

He said [slashdot.org] he disabled administrative access from outside.

Given the level of competence he has displayed I frankly suspect that he failed to do that correctly or, if he did, he probably ended up blocking access from outside the ISP subnet.

Finally, even disregarding all that, even if he was stupid and careless, they can't just access the router if he didn't explicitly give them the right in a contract somewhere.

He probably did - there is usually some clause somewhere where you agree to let them take action to prevent security breaches or some such. Failing that there is always a clause which lets them disconnect incorrectly configured hardware which poses a risk to the network which this arguably does. So would you advocate disconnecting the router and sending letter that customers have to reconfigure the default password before it will be allowed to reconnect? It's hard to see how anyone can complain about their actions. There is no private data stored on the router nor did they change any setting beyond the minimum needed to secure it. This is the sort of thing that a sysadmin does for you and that people usually say "thank you" for.

Re:uhhh

[darthwader]

I purchased a combination lock for my front door three years ago. Today, saw a note on my kitchen table from the locksmith. I said "I noticed that the lock I sold you three years ago still has the default combination on it. That's really insecure, so I changed it to your phone number. No need to thank me."

Did the locksmith do anything wrong by breaking into my house to change the combination on the lock?

Verizon can probably get away with this, because on page 239 of the user agreement he signed it says "Verizon reserves the right to do anything we want to you and your property, forever, because we know you won't read this far into the agreement, you're just going to sign it after skimming the first page. Sucker." But still, even if the poster did agree to this in a user agreement, Verizon should NOT be hacking into and reconfiguring other people's equipment, even if they think it's a good idea.

Re:uhhh

[INT_QRK]

I got the same message from Verizon FIOS. All I can think to say is, "thank you Verizon" for being proactive in addressing an identified security issue about which I was previously unaware. Please keep up the due diligence.

Re:uhhh

[Anti_Climax]

What are you all on about? He said [slashdot.org] he disabled administrative access from outside. No matter the password, there's intrusion going on here, so there is something to talk about.

Administrative access was not used for this. His actiontec, along with most other telco distributed CPEs use the TR-69 remote administration spec to allow for reconfiguration of services, firmware updates and other crap that used to require a technician to be sent out.

If a password was all there is to protect your router from outside, all hell would break loose for simple brute forcing. You also can't expect Aunt Irma to change her password first thing when she gets net access.

Which is why they changed his password from the default to a unique one. Even with remote access disabled, a default password on your router is a risk. see Pharming

Finally, even disregarding all that, even if he was stupid and careless, they can't just access the router if he didn't explicitly give them the right in a contract somewhere. I get you're all supercomputerexperts, but maybe we could talk about what he's asking?

Telcos are typically behind IBM and God on how many lawyers they have on staff. I'll eat my fucking shoe if it's not explicitly laid out in the TOS for FIOS that they can and will access the router for remote configuration changes, particularly for security reasons.

Why is there an open forced access port/back door?

There is a backdoor to allow changes in configuration that are usually, but not always, related to connectivity and function of the actual connection to the provider - the minutiae that even a field tech doesn't want to have to waste time with.

Is that ok without telling the owner?

Are we that sure it wasn't in that contract he signed?

What security is in place that entities besides Verizon can't access it?

A properly implemented TR-69 system is going to be more secure than any machine this guy is running on his network, guaranteed. The administration server address cannot be changed from the user accessible interfaces, the connection is initiated from the CPE to that server instead of the reverse and there are multiple layers of verification and encryption in use before anything is actually allowed to be updated or changed.

Re:uhhh

[luca]

What are you all on about? He said he disabled administrative access from outside.

He disabled the user visible administrative interface.

Google for tr69 and you'll be enlightened.

In my router it's impossible to disable, however in some normally hidden menu I could modify the "call home" url, rendering it ineffective.

Re:uhhh

[jcostom]

Interesting.. When we first got FiOS, they were only doing Internet & Phone (TV came 2 years later), and handing out D-Link routers. Since I work for a network manufacturer, the first thing I did was swap it out for a real firewall. 2 years later, they started doing TV in our area, they brought out an Actiontec, wanting to replace my firewall with theirs. Fortunately, I came upon a solution that worked perfectly, and doesn't involve using their router directly (shocked the installers that came out to do our TV install). I've got the Ethernet WAN port of their router plugged into an isolated zone on my firewall (where my Guest WLAN also lives), with the cable wire still connected (so the cable boxes can get guide data). This isolated zone has access to the Internet only, nothing on my "regular" network at all. Works like a champ. Get your FiOS Internet delivered over Cat5 if you can get the installer to do it, then hook up the router that way. The cable boxes don't seem to mind 2 layers of NAT, so I see no reason not to deploy like this.

Re:uhhh

[SuperTechnoNerd]

My friend works for Verizon and warned me about port 4567 so I blocked it as soon as I got the service. This is scary because they can install any software on your router at any time.. Even to monitor your traffic on you LAN side. Even though I blocked the port, after hearing this, now may get rid of the actiontech, although it is a nice router.

Bad analogy, since this is leased equipment from Verizon, it's more like you rent an apartment and the landlord changes the busted up locks on your door or performs other various maintenance on their property for you. If you haven't rented before, I can tell you that is quite normal.

Re:uhhh

[someone1234]

That password was owned by Verizon. He should have changed it to 'own' it, but he didn't.

This situation is like: you go into the shop, pay for some item but leave it on the counter.
The vendor notices it, runs out of the shop and hands it to you, again.
You scream a hissy fit that the vendor dared to touch YOUR ware.

He should have learned from this lesson and not be a dick and post this on Slashdot.

Then change your password

[Anonymous Coward]

Maybe they were able to change it because you were too lazy to do it in 3 years. For the first time, I think Verizon did the right thing in this case instead of letting stupid users be online and get potentially hacked and become a nuisance to the internet.

Putting things in perspective

[BondGamer]

You had kept your password as password1, yet are complaining about Verizon being able to change your password?

Re:Putting things in perspective

[PinkyGigglebrain]

I think his concern is that Verizon was able to change it from the outside.

That he left it with such a weak password is beside the point. The routers I've worked with will not allow administration level access over the outside port or wireless connection unless explicitly allowed by the admin, so Verizon being able to do just that should raise a few questions.

He owns the router, right, and yet Verizon thought they had the right to log in and change his password.

Makes me wonder if they have a firmware coded backdoor/admin password into the router.

Perhaps a little cheese with that whine?

[wiredlogic]

Every broadband provider has access to the modems connected to their network to perform maintenance and updates as necessary. It's part of the fine print you agreed to. If you didn't want them getting into your router configuration you should have changed the default password.

Re:Perhaps a little cheese with that whine?

[thestuckmud]

My provider allows third party modems. Absent a conspiracy between manufacturers and providers, there is no way they can force updates on my equipment.

You are correct about the fine print, though. They reserve the right to update their software on my equipment (including computers). The simple solution there is not installing their software in the first place.

I'm upset

[OverlordQ]

I am upset about this because Verizon should not have any way to get into my router and change the settings, especially because I own the router, not them!

I'm upset they let people like you on the internet. Change your passwords from the default and use something secure. Instead of waiting for somebody to do something fun like log in remotely to your router using the default login and hosing your settings so your internet goes down.

Ummm...try changing the password!

[mhkohne]

If you don't want them to access the router, change the bloody password. Like you should have done 3 years ago!

Re:Ummm...try changing the password!

[fuzzyfuzzyfungus]

There is no particular reason to suspect that changing the password would alter their level of access.

On most consumer routers, "the password" is what controls access to the dinky webserver serving the configuration interface, on port 80, LAN side only. According to TFS, Verizon's pet routers have something listening to port 4567, WAN side. There is no particular reason to believe(and, indeed, reason to disbelieve) that the password controlling access to the port 80 web interface and the access control mechanism on the port 4567 WAN management interface are at all connected. Assuming they aren't total morons, I'd imagine that they would use some flavor of keypair auth for that one.

We would need somebody to grab the firmware for the router in question and have a look to actually settle the issue.

Re:Ummm...try changing the password!

[fuzzyfuzzyfungus]

I don't have access to one of these routers to check; but googling around for "port 4567 verizon" returns all sorts of hits, the gist of which is that this "feature" is on by default and cannot be turned off. In what I imagine is an oversight on Verizon's part, it is apparently possible to set a firewall rule that blocks that port, which is the closest you can get to disabling it in the default firmware.

As for what it is capable of, reports suggest that it can be used for firmware updates, and TFS suggests that it can see(and change) password hashes on the system. If it can do that, it seems reasonable to assume that it can probably access the entire local filesystem on the device. Further, if it can update the firmware, Verizon could always push a firmware update giving their remote management interface any powers that it currently lacks.

In addition to unnervingly paternalistic, but more or less benign, firmware updating and password securing; it isn't exactly tinfoil-hat territory to postulate that it might be used for market research(number of devices/household, manufacturers, determined by MAC, of those devices, etc.)

I would assume, though, that any heavy network monitoring/secret sinister CALEA/NSL stuff probably isn't handled on the router. Verizon, being your ISP, controls the other end of the connection(and, unless you take specific steps to the contrary, is your DNS provider), so they hardly need to build any serious spying power into their routers(especially since that would raise BOM cost for a device that they order millions of, and expose their sinister program to anybody with some basic linux hacking chops who either downloads and disassembles the firmware, or snags a used router on ebay, or signs up and investigates his own router(and, given that techies are more than usually interested in high-speed internet, the odds are very good of this happening). Therefore, I would expect that this management interface offers an upsettingly comprehensive set of functions for controlling the router and accessing its filesystem; but contains no overtly sinister embedded logic. Any of that that exists would be closer to the center of the network.

You're joking, right?!

[dave562]

Your router was set to the default password after 3 YEARS and you're claiming to be upset that Verizon secured it for you? Are you kidding me? I'm all for letting people wallow in their own stupidity and ignorance, but come on buddy. They did you a favor. In all seriousness, they shouldn't have left it default in the first place. It should have been set to your serial number from the factory.

Wow... retards abundant

[Raxxon]

I have Verizon FIOS. Tech came out to make sure everything worked and told me that despite the fact that I am a network engineer and it is a Business Class account that he was required as part of his job to install their crappy router and verify connectivity with it. I allowed him to do it and 20 minutes after he was out the door I had my router in place and everything secured to my specifications.

Funny enough, I haven't been contacted by Verizon about the fact that my router is insecure or has default passwords. They haven't changed the password(s) on my router or reconfigured anything other than when I called them 2 weeks ago to make them give me more speed for less money (Packages changed, double the bandwidth I had for $15/mo LESS).

Please contact Verizon, ask them to cancel your service and GTFO the internets plz.

This is News for Nerds, Stuff That Matters?!?

[djlowe]

Hi,

I checked and it actually had been changed.

OMG! So, you tried the new password, and it worked? Why didn't you change it then? More importantly: Why didn't you change it the first time?

I am upset about this because Verizon should not have any way to get into my router and change the settings, especially because I own the router, not them!

No, you're upset because you are clueless, though you think you are not, just discovered it and are pissed off because your router had the same password for 3 years as a result, and Verizon was forced to change it because you were too ignorant to do so yourself earlier.

I looked in the router's settings and I see port 4567 goes to the router and is labeled 'Verizon FIOS Service.' Is this port for anything useful other than Verizon changing settings on my router? What security measures does Verizon have to protect that port from unauthorized access?"

I imagine they at least understand the importance of password security, where you apparently did not.

It is so beautiful though. I have thoroughly enjoyed this thread. The innocent naivete of the original poster. The confusion of the geeks wondering if such incompetence is truly possible in someone who figured out how to post a Slashdot story.

Slashdot should start a new Sunday feature, call it, "Is it Real?" or something, where they post stories like this and make us try to guess if the original post is real or not.

This man (original poster) should never change. He should preserve himself as he is, so all of us can look at him and wonder, how is such a thing possible. It is a sterling example of what the human race is truly capable of.

The opening line is the best, let me quote it again just because it makes me laugh out loud every time I read it:

I have Verizon FIOS at home and my Verizon-supplied Actiontec router had the password 'password1' that the tech assigned to it when he set it up three years ago.

At least you knew your password

[IBBoard]

At least you knew your password! Sky in the UK ship out Netgear routers and don't tell you the password. I "brute-forced" it in about three attempts, but that's not the point (in fact, perhaps it is, since it was something like "admin" and "sky"!).

The worst part was that we later complained about speed issues on the line and they got back to us saying "sorry, we seem to be having problems accessing your router". Erm, yeah, that'd kinda be the point - I don't want my router open and available with any backdoors on the Internet!

Erm.... TR-069, anyone?

[jimicus]

AFAICT, many ISPs that supply their own routers are actively looking at (if they're not already) supplying routers which support TR-069 and setting up infrastructure to configure them.

This is a protocol intended for the management of home routers - unlike SNMP, it's got some semblance of security (it's actually based on SOAP over HTTP, optionally HTTPS) - IIRC the CPE initiates the connection and can get things like configuration and firmware upgrades automatically.

I don't see how this is drastically different in concept from cable modems, which are more-or-less invariably heavily managed using DOCSIS.

Yes, I do. And have. However, if an update borks my connection, I'm shit out of luck as far as support from them is concerned. (I made a point of looking at my TOS when I did the update to make sure they couldn't kick me off for doing it).

They were kinder than you deserved

[SuperKendall]

After three years, they changed the password to something you could easily find just by looking at the device.

I would have changed the password to something totally random, and made you sit through four hours of voice menus on the phone to figure out what the new one was, for fear you would change it back.

Verizon deserves a medal for restraint on this one.

Re:RTFA

[BlackWind]

If the guy has Verizon FiOS, and is using the ActionTec router that was installed as part of the service, he does not own it. Verizon does NOT sell the router to the customer. (Buying the router is never an option.)
Verizon supplies the router to support TV & Internet services over FiOS, and Verizon will repair or replace the router at any time that there is a problem with it without charging the customer. (With the exception of incidents of vandalism, or a pattern of abuse requiring multiple swaps of the router over time.)
[I currently work for Verizon, and install FiOS every day. (Yes, the majority of the STUPID configuration decisions are forced on us by management to save time & effort from dealing with the average tech knowledge of both customers and other technicians with little or no knowledge about networks or security.)]

A matter of necessity

[GothPanda]

I used to work for a call center that did the tech support for Verizon DSL. We had an internal system that's responsible for line testing, and this system also let us push changes equipment we've provided. Most agents didn't know how to use the functionality of this system, but it's almost required, because some customers aren't able to change the settings with or without our help. "We need you to reset your modem. Hold down the little button on the back. You can't find it? You don't know how a button works? Fine, just let me do it from here." To OP, it's a modem that happens to have a router, not just your router. You may own the equipment, but it's still connecting to the Verizon Network, and since Verizon provided the equipment, they're going to make sure that they can make it work if you fraked it up.

Yes, but...

[Jane Q. Public]

The "regulated monopoly" of the phone lines was actually a huge success story for the United States. While we were building a coast-to-coast, 100% compatible and interoperable, relatively inexpensive telephone system, most other countries that had competition in that market ended up with multiple incompatible systems. In many cases you could not call your neighbor down the street, because he was on a different phone system that didn't play nice with yours. There were huge redundant mazes of wires overhead, belonging to different companies and systems, and completely incompatible switching systems. Often they operated at very different voltages and current.

Of course, since then the situation has been straightened out in most countries. Nevertheless, for decades the regulated monopoly gave us tremendous advantages that "free market" competition could not and did not achieve in those other countries. I am generally not one to support laws and regulation but that is the factual, undeniable history.

If it were not for the fact that Bell blatantly violated court orders, and greedily used its given monopoly of the lines to also create a monopoly of hardware, we might very well still be on a universal Bell system. Which would not be good: the breakup occurred at a fortunate time, when the technology actually allowed competition in the hardware. But it should be noted that after the breakup, when competition was allowed in the area of infrastructure (telephone lines), prices did NOT go down! Phones got better and cheaper, but access did not.

For something like phone line infrastructure, and now network infrastructure, the regulated-monopoly model is actually a very good and workable one. Of course we already had competition in network infrastructure, so establishing a regulated monopoly is probably out of the question. But what we have is a few big players, not many small ones. So it may not be a monopoly, but it's definitely an oligopoly, which is nearly as bad. Surveys of other countries that have better network access (i.e., cheaper and faster), show very clearly that laws mandating leased access to infrastructure, so that the "little guys" can participate, is essential to opening up the market and gaining the benefits of actual "free market" competition. Allowing the oligopoly to remain has already caused the US to fall behind much of the developed world in network infrastructure. If we continue to allow that, without mandatory leased access to the infrastructure, we will only continue to fall farther behind.

Re:You failed to consider: this person is clueless

Every ActionTec router from Verizon that i've encountered (a dozen or so) had remote administrative access disabled by default.

TR-069 TR-098

[dogsbreath]

Not taking sides here but for an explanation of what is going on, you might want to look at Motive's HDM (home device management) application which works with TR69 enabled devices. I am not a Verizon customer so I don't know what the service EULA looks like but if this was a Verizon supplied device then it is likely enabled for some home device management system and such management is OKd in the service agreement. Again, I am just making some assumptions here and not saying this is kosher.

TR69 devices register with a pre-determined server when they are powered on and go through an ISP determined process to do things like password setting. If you could sniff the line side, you should see an initial HTTPS session briefly set up, pass some traffic, and then shut down.

You might want to google TR-098 which is the Internet Gateway device specification within TR-069

http://www.broadband-forum.org/technical/download/TR-098_Amendment-2.pdf

http://www.actiontec.com/products/datasheets/MI424WR%20Verizon%20FiOS%20Router%20Datasheet.pdf

Companies like Verizon and (I believe) British Telecom have gone this route to drive down help desk costs by enabling managed firmware upgrades and remote parameter setting of a subscribers device. ie Subscriber calls and complains "my internet is broken"; Tier I help desk remotely resets the subscriber's router to the original configuration and voila: the internet is unbroken!

HDM systems also gather metrics from the subscriber routers.

As far as the ISP is concerned, your FIOS/Cable/DSL router is the same as a TV set top box or satellite receiver. Cable and IP STBs are capable of sending back extremely detailed stats of anything that happens on the box, including your viewing habits.

From the ISP point of view, this gives them a powerful tool to deal with systemic failures due to firmware bugs, network attacks, and user finger problems. It also provides a method of getting network stats back from the field devices so that an overall picture of network health can be evaluated. Most subscribers will have no clue what is going on and mostly don't give a fig.

Safest approach is to assume that the access layer router is owned (in the control sense) by your provider and put your own security layer below it. Be warned that you likely can't put your IP TV STB behind your own security layer unless you make sure it can pass multicast.

Again, I am not saying this is hunky-dory but it is what I have seen.

Port 4567 can't be disabled

[robot5five]

For reference port 4567 is listening on the OUTSIDE interface...the side that faces the internet. This came to my attention some time ago when I decided to switch from Comcast to Verizon. I did a tad bit of research when I was in between jobs and kept a blog on my adventures with port 4567....that CAN'T BE DISABLED. There are ways to keep verizon from spying on you and illegally entering your computer network. My blog posts are here: http://robot5five.blogspot.com/2009_07_01_archive.html Cracking the password hash was trivial, although it took me a little time until I found several other folks had already done it.

He does have a problem with a bad password, there are some fairly clever javascript attacks that target exactly this situation, remote admin disabled and all.

The web browser is tricked to connect to a default router address (like 10.0.0.1) with a default login (admin/password1) and changes whatever settings it wants, perhaps just opening remote administration. Because the connection to the router comes from the local PC this isn't "remote" administration. There are few enough possible combinations that you can brute force the default login really easily and enough people with default set ups to make it very worth while.

If Verizon has all of their customers with the same router, the same network setup and the same password... it would be negligent not to do everything they could to help protect their customers.
