[Full-disclosure] Cisco CS-MARS Clear Text Password Storage - v6.0.4 and Earlier

1. First after logging onto the console either pnlog mailto, or pnlog scpto
will send the logs off of the box to a destination you specify, you can also
display the logs using pnlog show.

[pnadmin]$ pnlog scpto ryan@xxxxxxxxxxx:/home/ryan
scp /tmp/error-logs.tar.gz ryan@xxxxxxxxxxx:/home/ryan/error-logs.tar.gz
The authenticity of host '10.4.61.206 (10.4.61.206)' can't be established.
RSA key fingerprint is cc:c5:35:ad:be:16:4e:59:6a:48:90:c3:98:9f:a3:e4.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '10.4.61.206' (RSA) to the list of known hosts.

2. After transfering the logs two files are produced as shown below.
root@ultidesk:~/logs# ls
error-logs.tar.gz  janus-logs.tar.gz
root@ultidesk:~/logs#

3. After extraction the following files are created as well as a folder
structre within the folder you copied the log files to.
root@ultidesk:~/logs# tar -xvf janus-logs.tar.gz

3. Now executing grep for a portion of the password that MARS uses to access
Windows Devices (password masked with ####). We can see that in this case
every iterration of sysbacktrace.X containes 30 occurances of our password
(95 files 30 occurances each = 2,850 occurances of our password):

it includes the system ip, the domain, the username and the password.
(Username, domain, and password have been masked with ###).

5. Granted access to the sysbacktrace logs is only possible with ssh access
to the box however these logs if attached to a support ticket through email
are sent in the clear, or if these log files are routinely dumped and stored
the password is avliable in clear text. Additionally in most cases MARS will
be monitoring Active Directory data in order to access Domain Controllers
'Domain Admin' rights must be included in the account.
