Cisco Unified Communications Manager Improper Access Control (cisco-sa-ucm-access-dMKvV2DY)

high Nessus Plugin ID 163081


The remote device is missing a vendor-supplied security patch


The version of Cisco Unified Communications Manager installed on the remote host is 14.x prior to 14SU2. It is, therefore, affected by an improper access control vulnerability. An authenticated attacker with read-only privileges can exploit this vulnerability to perform a set of administrative actions they should not be able to.

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