Cisco Unified Communications Manager Privilege Escalation (cisco-sa-cucm-priv-esc-D8Bky5eg)

high Nessus Plugin ID 180547


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


The version of Cisco Unified Communications Manager installed on the remote host is 12.5(1)SU8 and missing a security patch. It is, therefore, affected by a privilege escalation vulnerability due to the lack of restrictions on files that are used for upgrades. An attacker with administrator privileges can create a specially crafted update file to elevate their privileges to root.

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