Synopsis
The remote device is missing a vendor-supplied security patch.Description
The Cisco Expressway Series or Cisco TelePresence Video Communication Server (VCS) running on the remote host is 14.x prior to 14.3.0. It is, therefore, affected by a privilege escalation vulnerability as described in the cisco-sa-expressway-priv-esc-Ls2B9t7b advisory. Due to an incorrect implementation of user role permissions, a local attacker with administrator read-only permissions can execute commands beyond the sphere of their intended access level, including modifying system configuration parameters.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.
