Synopsis

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

Description

According to its self-reported version, the instance of Cisco TelePresence VCS installed on the remote host contains vulnerabilities in its cluster database API and its web-based management interface due to insufficient input validation of user-supplied command arguments. An authenticated, remote attacker with read/write privileges can exploit this issue, by sending crafted requests, to overwrite arbitrary files on the underlying operating system as the root user.
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.
