medium Nessus Plugin ID 148643
New! Plugin Severity Now Using CVSS v3

The remote device is missing a vendor-supplied security patch


According to its self-reported version, the Self Care Portal of Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) is affected by authorization bypass vulnerability due to insufficient validation of user-supplied data to the Self Care Portal. An authenticated, remote attacker can exploit this by sending a crafted HTTP request to an affected system. A successful exploit could allow the attacker to modify information without proper authorization.

Please see the included Cisco BID and Cisco Security Advisory for more information.

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