Descriptions

A vulnerability in the management of shell user accounts for Cisco Policy Suite (CPS) Software for CPS appliances could allow an authenticated, local attacker to gain elevated privileges on an affected system. The affected privilege level is not at the root level. The vulnerability is due to incorrect role-based access control (RBAC) for shell user accounts. An attacker could exploit this vulnerability by authenticating to an affected appliance and providing crafted user input via the CLI. A successful exploit could allow the attacker to acquire a higher privilege level than should have been granted. To exploit this vulnerability, the attacker must log in to the appliance with valid credentials. Cisco Bug IDs: CSCve37724. Known Affected Releases: 9.0.0, 9.1.0, 10.0.0, 11.0.0, 12.0.0.
