Synopsis

The remote device is missing a vendor-supplied security patch

Description

The version of Cisco Unified Communications Manager (Unified CM) is affected by a vulnerability in its web-based management interface that allows an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the operating system.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
