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

[Pete Brown]

If you have an affected lab box, any chance you could package up few files and send them over off list?

I was thinking about running John the Ripper on a lab box that is affected to try to get the password.  Not sure if it will find anything though.

I wonder if there are any existing penetration testing utilities to check for these conditions on UCOS hosts?


If not, challenge accepted.

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!
