SYSTEM code execution via unauthenticated NAM function
Published May 15, 2024 · Updated Aug 1, 2024
Privilege escalation in Cisco Secure Client for Windows before 5.1.3.62 allows physically proximate attackers to execute code as SYSTEM. The Network Access Manager module exposes a specific critical function without authentication, but Cisco has not identified the function or its input. Physical access and an installed NAM module are required; Linux, macOS, and mobile clients are not affected.
