'Tens of millions' of Cisco devices vulnerable to CDPwn flaws: Network segmentation blown apart by security bugs


Re: Rule #1 -- Beware of home made protocols

Interesting that IOS & IOS-XE aren't vulnerable according to the CVE which means it's not the actually the protocol but the software implementation of it on other platforms. NX-OS, IOS XR & FC-OS are all Linux based. Where IOS is BSD based and IOS-XE is Linux based running IOS as a process called "IOSd".
