According to its self-reported version number, the software upgrade process of Cisco Unified Communications Manager (Unified CM) and Cisco Unified CM Session Management Edition is affected by an arbitrary file write vulnerability. An authenticated remote attacker can exploit this vulnerability to write arbitrary files on the affected system with root-level privileges.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
