The Web's 20 Worst Security Flaws

XsynackX writes "The SANS Institute released its Top-20 list of the biggest vulnerabilities on the web today. The SANS Top 20 Internet Security Vulnerabilities list is actually a compilation of two lists--the top 10 Windows vulnerabilities and the top 10 Unix vulnerabilities. The list goes into almost more detail than any one person could ever take in on individual security flaws, but provides a wealth of knowledge for those who like to get in-depth. Interestingly enough, the browser section of the Windows vulnerabilities lists everyone's favorite browser Internet Explorer with 15 flaws and Mozilla with only 7."

not just "the web"

[UnderAttack]

These flaws cover more then just "the web".
They include things like week passwords and non-web network threats.

Re:not just "the web"

[pjt33]

But surely changing your passwords every week is good? (Well, against external attackers - not so good against internal attackers if you have to write your password on a PostIt and stick it to your monitor).

Re:not just "the web"

[tomsuchy]

NEVER stick your password post-it on the monitor! It goes under the keyboard.

NEVER stick your password post-it on the monitor! It goes under the keyboard.

That's precisely why you should stick it to the monitor - nobody will find it because they will be busy looking under the keyboard! Cunning, eh?

Re:not just "the web"

[DarkSarin]

Remember this: if the attackers have physical access to the machine, there is almost no security to speak of. You may be able to limit access to one machine at a time (thus preventing intranet assualts), but once an attacker is sitting at the computer in question, there is very little that they cannot do. This is true for both windows and linux. Even password theft is possible on Linux, given the right amount of time.

Certainly some attacks take longer, but in general, if they have your machine, its too late for security!

Firefox vulnerabilities IE vulnerabilities

[thre5her]

Fortunately for now, security through obscurity prevails for Firefox, since most exploits will likely target IE users. However, Firefox's development model is inherently better than IE's with regards to security, since the status of these vulnerabilities is known to all and they are fixed much more quickly. Why Microsoft is still in the browser game with their lame, few-and-far-between updates is beyond me.

Only 7?

[cperciva]

...Internet Explorer with 15 flaws and Mozilla with only 7

Err... at this point, does it really matter? It's useful to compare BIND against djbdns (many security flaws vs. none), or Linux against OpenBSD (many security flaws vs. one remote hole in 8 years), but 15 flaws vs. 7 flaws? To me, that just says that both browsers are horribly insecure, and slightly more effort has been put into finding flaws in MSIE.

Re:Only 7?

[endofoctober]

The numbers may not matter, but the response to the threats from both organizations matters very much. Of the 7 flaws in Mozilla, all have been fixed as of Moz1.7/FF.9 whereas of IE's 15 vulnerabilities, only 6 have vendor patches.

Re:Only 7?

[ArbitraryConstant]

OpenSSH is on by default in OpenBSD. The one hole in 8 years was in OpenSSH. OpenSSH is the only service visible to the outside that's on be default.

The forked Apache in OpenBSD is much more secure than any you'd find elsewhere. On top of all the patches rejected by the Apache people for various reasons and thus not distributed to anyone else, it benefits from W^X protection (on i386, which no one else has) and ProPolice (it's not that widely used, some of the userspace stuff in Linux seems to use it but the kernel doesn't). This has turned a bunch of arbitrary code exploits into DOSs, which merely crash the server process.

The ftpd in the base install as well as everything else benefits from W^X and ProPolice. W^X is handled by the system, and ProPolice is used by default on anything you compile. Therefore, unless you work pretty hard to avoid it, anything that's run on OpenBSD benefits from the added protection. As a result, it's more secure because exploits aren't always exploitable on the platform.

DOS issues are still patched, but the difference is that they're not exploitable before the patch is issued.

Their web server...

...seems to feel that posting a link to it on slashdot is a vunerability.

Ok I'm sure I'll get slammed for this but...

[otlg]

Doesn't everyone that reads /. know that MS IE is a gaping security vulnerability by now. Do we *really* need to keep harping on it like a bunch of smug self-righteous motherfuckers?

Yes, because it makes our penises feel bigger.

In my oppion

[Ziak]

I've always said that spyware was caused due to Internet Explorer being so popular.... If firefox keeps the rate of growth its doing I don't think it will be that long into we see spy/malware targeting Firefox as well....

Re:In my oppion

[ttldkns]

Crack sites and (my friend told me this) some pron sites used to have XPI install spyware (but you had to click ok to install it).

This was fixed by the mozilla dev team's implementation of a XPI installer website whitelist consisting of (by default) just mozdev.org. The user can add other sites though, should they want to.

Re:In my oppion

[Space_Soldier]

That is not entirely true. It is well known that Microsoft abandoned IE after it has won the first browser war. Microsoft have also had a unsecure programming mindset because they started as one-user-minded company instead of multi-user-minded company. Because they did not care about security at first, now they are paying the price. Unfortunetly, the consumer is facing the heat worse than Microsoft.

Firefox does not allow extensions to be installed from another web site besides update.mozilla.org by default. The user must specify in the options that it wants to allow extensions from a certain site to be installed, which should keep spyware low for now. Firefox users also have more computer skills than IE users. Firefox holes are filled faster than IE. All this should keep spyware low on the Mozilla platform.

PS: I believe that a recently passed bill made spyware illegal with the penality of prison, and I think that I saw on Google news something about the first spyware trial.

7 is not `only'

[mukund]

Interestingly enough, the browser section of the Windows vulnerabilities lists everyone's favorite browser Internet Explorer with 15 flaws and Mozilla with only 7.

Don't think I'm trolling but this is like saying the USA has 27,000 nuclear weapons whereas Russia has only 13,000.

Re:7 is not `only'

[ricotest]

Also, 'flaw' is stupidly vague. There's a big difference between 'sometimes the Slashdot page isn't rendered correctly' and 'a JPEG image allows remote code execution'. From a quick look at the article, however, it covers 'vulnerabilities' which is more specific: data loss, remote code execution and crashes.

Still, I agree with the parent - this is an AvP situation. Whoever 'wins' with the least problems, we still lose.

Re:7 is not `only'

[fireboy1919]

RTFA. It's more like saying that USA has 27,000 nuclear weapons and Russia has 13,000, but they've all been disarmed.

Not only do the Mozilla vulnerabilities not actually allow much of an attack, but they've all been fixed in the latest versions of the browser.

This is not true on the Windows side, as Secunia recommends disabling or switching browsers to deal with a lot of the bugs.

That should be...

Top Vulnerabilities to UNIX Systems
1. A fool with root access.

You were going for the Funny mod, right?

[wasted]

If not ...
The article separately lists the top 10 Windows and top 10 Unix vulnerabilities. In this case, Top 10 plus Top 10 does not necessarily equal Top 20.

Sort of like if you considered the Top 10 fastest race cars at a Nascar race and the Top 10 fastest race cars at a soapbox derby race - the resulting list wouldn't be the Top 20 fastest race cars.

Only?

[powerlinekid]

...everyone's favorite browser Internet Explorer with 15 flaws and Mozilla with only 7.

I don't think security flaws in something as commonly used as a web browser should ever be noted as "only" a certain number. Sure Mozilla beat IE, but the point still remains that it had 7 too many. I'll have to read this list when I get a chance and see how many of those were really windows issues and mozilla just passed the data on.

(And yes I know you'll never have bug free software)
