Root code execution via planted library loading
Published Mar 6, 2024 · Updated Aug 1, 2024
Privilege escalation in Cisco Secure Client for Linux before 5.1.2.42 allows local users to execute code as root through ISE Posture. The ISE Posture System Scan process searches an uncontrolled filesystem location and loads a planted library when an administrator restarts it. Exploitation requires a locally authenticated user to place the library in that directory and persuade an administrator to restart the affected process.
