Title
Local Privilege Escalation via IPC Broker Impersonation in TeamViewer Remote Management Monitoring for Windows
Summary
Improper authentication in the
inter-process communication (IPC) mechanism of TeamViewer Remote Management
Monitoring for Windows prior to version 26.10.1 allows a local authenticated
attacker with low privileges to impersonate the IPC broker and cause the
Monitoring service to execute arbitrary code with NT AUTHORITY\SYSTEM
privileges, resulting in local privilege escalation.
Severity
7.8 (High)
