Synopsis
The remote device is missing a vendor-supplied security patch.Description

It is, therefore, affected by a privilege escalation vulnerability as described in the cisco-sa-expressway-priv-esc-Ls2B9t7b advisory. Due to incorrect handling of password change requests, a remote attacker with read-only administrator privileges can alter the passwords of any user on the system, including those with administrator read-write access.Please see the included Cisco BIDs and Cisco Security Advisory for more information.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
