[cisco-voip] Cisco Voice Operating System-Based Products Unauthorized Access Vulnerability

[Ryan Ratliff (rratliff)]

I’d rather you take the approach of telling all of your customers to install the COP file rather than pen-testing on a live system :)

If you want to see if they are exposed get the system-history.log and install.log and upload them to a TAC SR or manually inspect them to determine the timeline of install & upgrade types. All the info you need is in the advisory.
PCD Migration -> exposed
RU Upgrade -> exposed
L2 Upgrade -> not exposed

Anyone got some ideas on trying to crack this UCOS password?  Should help us out in scanning our customers to see if they are affected, but we wouldn't want this password to end up indexed by google and make the issue even worse.

Bwahaha! I just logged in to your CUCM Tim.

On a serious note, I think it’s interesting how this “flag” issue is such a big deal, when back in the old days of UCCX, Cisco was creating an intentional back-door in all installs, using the same username and password on all of them.

For the curious, it was :

Username: CRSAdministrator
Password: NwY.t9g(f'L9[3C

If you have access to a UCCX 7x or lower, try logging in to Windows with that account and report back if it worked.

If it does work, check the MADM logs on the C: for the clear text AXL username and password, so you can compromise CUCM too!
