Lenovo Discovers and Removes Backdoor In Networking Switches (bleepingcomputer.com)

Posted by msmash on from the fixing-things dept.

An anonymous reader writes: Lenovo engineers have discovered a backdoor in the firmware of RackSwitch and BladeCenter networking switches. The company released firmware updates last week. The Chinese company said it found the backdoor after an internal security audit of firmware for products added to its portfolio following the acquisitions of other companies. Lenovo says the backdoor affects only RackSwitch and BladeCenter switches running ENOS (Enterprise Network Operating System).

The backdoor was added to ENOS in 2004 when ENOS was maintained by Nortel's Blade Server Switch Business Unit (BSSBU). Lenovo claims Nortel appears to have authorized the addition of the backdoor "at the request of a BSSBU OEM customer." In a security advisory regarding this issue, Lenovo refers to the backdoor under the name of "HP backdoor." The backdoor code appears to have remained in the firmware even after Nortel spun BSSBU off in 2006 as BLADE Network Technologies (BNT). The backdoor also remained in the code even after IBM acquired BNT in 2010. Lenovo bought IBM's BNT portfolio in 2014.

      There is only one FISC and it doesn’t actually give out orders. If you’re gonna try to create a conspiracy at least gets your facts straight.

      Yes, and those are written up and issued by the FBI not the FISC. The whole point of the NSL is not needing court approval. Want to try again?

      Neither the FISA court nor any court is involved in NSLs. That’s one of the major issues with them; the complete lack of any (even rubber-stamped) judicial oversight.

    TFA says they are calling it the "HP backdoor", but it was installed by Nortel at the request of Enterprise customers (government ones?). Is this just a nice attempt to smear HP? As an ex hp'er I approve, but I'm curious.

      Not an "enterprise" customer but a customer that embeds the switches in their own product or solution, hence the term OEM. Presumably HP requested the backdoor for some reason (ex. easier support, CIA request, etc) and Nortel complied.

      I guess it's pretty funny to name the backdoor after the requester. Allegedly.

    So, around about 2002, Nortel got hacked by hackers in China. This hack was not completely dealt with for at least ten years.

    So,... How was this vulnerability discovered? Could it have been "discovered" by its creator?

      There is enough possibility left open, that RTFS doesn't quite discredit the implication I suggested. This was added to ENOS during a time when someone in China had a full backdoor into Nortel's systems, which apparently went undetected until 2004, and was not fully detected at least until 2012. http://www.zdnet.com/article/n...

      This might have been requested by HP, as another commenter suggested elsewhere, and then incompetence spread it to equipment beyond the requester's equipment. Or it could have been compromised code planted by the hackers, hiding it as HP requested code. Yet another option is that this was code intended for HP equipment, which the hackers then approved for non-HP equipment.

      We also don't know if any of the hackers involved in the incident(s) from 2000-2012 are employed with Lenovo. It is logical to assume they would have valuable expertise and skills.
