Cisco Removes Backdoor Account, Fourth Incident in the Last Four Months (bleepingcomputer.com)

For the fourth time this year, Cisco has removed hardcoded credentials that were left inside one of its products, which an attacker could have exploited to gain access to devices and inherently to customer networks. From a report: This time around, the hardcoded password was found in Cisco's Wide Area Application Services (WAAS), which is a software package that runs on Cisco hardware that can optimize WAN traffic management. This backdoor mechanism (CVE-2018-0329) was in the form of a hardcoded, read-only SNMP community string in the configuration file of the SNMP daemon. SNMP stands for Simple Network Management Protocol, an Internet protocol for collecting data about and from remote devices. The community string was there so SNMP servers knowing the string's value could connect to the remote Cisco device and gather statistics and system information about it.

      It shows Cisco is riddled with incompetent developers who are too stupid to get even the most simple hello world problem: "do not put backdoors in your work" wrong. So it doesn't matter if there is now a single guy on top who goes through all the code and makes them work it over. I means the developers there are too stupid to be trusted with anything. And all those lines by those same stupid developers are still in there. They still made the millions or even billions of LOC in Cisco firmware which Cisco cannot change, since it makes up the value of the company. They cannot change IOS suddenly to something that actually works without NSA backdoors and exploits.

      Also, we haven't heard or seen of any mass firing at Cisco, so these same developers who put in the backdoors last year will write the firmware for the Cisco router you want the public to buy next year.

      Stupid people generally don't get to become developers at Cisco.

      As a developer, I can say that most bad ideas such as these backdoors, originate from product requirements (sales teams, management, etc) and not from developers themselves. I'd bet that the developers in charge of implementing these backdoors did raise concerns and push back, but got the "my way or the highway" schpeel from their management.

      The NSA demands such support and it has to be done.

      Thats the very best way of thinking about it. Its just part of the product line. To help consumer, to help the NSA.

      The next options are much more fun.
      The NSA and other US agencies have placed staff in a lot of big brands who do this code "undercover" and live for every generation of product.
      Other US cyber contractors find the backdoor and report it the FBI.
      The FBI goes looking for the spies and finds a NSA operation domestically. The FBI looks around and finds a way in.
      The backdoor is removed much later but the FBI cannot comment of the NSA.
      Its all for global police requests. Police in different nations demand such access and backdoors. No backdoor and the export deals fails.
      So every export product ships with a police ready backdoor. Police around the world then allow their own respective gov to use the products.
      The NSA and FBI are happy with that.
      Rather then alert the world to many nations police deep in every network and computer system its just a "backdoor" that is discovered and reported on and nobody really know much.
