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.
