Published Jan 19, 2023 · Updated Aug 2, 2024

Privilege escalation in Cisco CX Cloud Agent 1.8 and earlier and 2.2 OVA installs allows local users to take control of the device. The advisory does not name the script or permission bits, but states that the insecurely permissioned script runs through sudo. An authenticated local account with permission to invoke the script through sudo is required, and successful exploitation grants complete device control.
