"According to its self-reported version, the Cisco Unified Communications Manager (Unified CM) and Cisco Unified 
Communications Manager Session Management Edition (Unified CM SME) are affected by information disclosure vulnerability 
due to improper inclusion of sensitive information in downloadable files. An authenticated, remote attacker can exploit 
this by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow 
the attacker to obtain hashed credentials of system users. To exploit this vulnerability an attacker would need to have 
valid user credentials with elevated privileges.

Please see the included Cisco BID 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
