"The version of Cisco Unified Communications Manager IM & Presence Service installed on the remote host is affected by a
remote code execution vulnerability due to improper sanitization of user-supplied input. An authenticated, remote
attacker can exploit this, by sending a SOAP API request with crafted parameters, in order to execute arbitrary code
with root privileges on the underlying operating system.

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