"A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM) and Cisco 
Unified Communications Manager Session Management Edition (Unified CM SME) could allow an authenticated, remote 
attacker to read arbitrary files from the underlying operating system. This vulnerability exists because the web-based 
management interface does not properly validate 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 underlying operating system.

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.");
