Summary
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.
There are no workarounds that address this vulnerability.
