Title
Privilege Escalation via Insecure Package Handling in TeamViewer Full Client and Host for macOS
Summary
A time-of-check time-of-use (TOCTOU) race condition combined with improper symbolic link handling in the privileged helper of TeamViewer Full Client and Host prior to version 15.83 for macOS allows a local attacker with low privileges to bypass installer package verification and install a malicious package. Successful exploitation can lead to local privilege escalation to root.
