Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, the Self Care Portal of Cisco Unified Communications Manager (Unified CM) is affected by a path traversal vulnerability in its web-based management interface due to a failure to properly validate user input. An authenticated, remote attacker can exploit this, by sending a URI that contains path traversal characters, to disclose the contents of files located outside of the server's restricted path.

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.

Solution
