Cisco Unified Communications Manager RCE (cisco-sa-cucm-rce-pqVYwyb)

high Nessus Plugin ID 148968

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of Cisco Unified Communications Manager 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.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCvu56491.
