Short explanation
Improper access control in TeamViewer Full Client and Host for Windows allows a local authenticated attacker with low privileges to supply a signed executable through a forged IPC response and gain NT AUTHORITY\SYSTEM privileges.
A low-privileged local user gaining NT AUTHORITY\SYSTEM privileges provides complete control over the system, significantly increasing the risk of full system compromise.
What should be done?
- Follow the vendor security bulletin
- Apply available updates
Chain of evidence and sources
TeamViewer Patch Management mekanizmasındaki zafiyet, düşük ayrıcalıklı yerel saldırganların NT AUTHORITY\SYSTEM yetkileri kazanmasını sağlar.

Show the technical text from the sources
Improper access control in the Patch Management update mechanism of TeamViewer Full Client and Host for Windows prior to version 15.82 allows a local authenticated attacker with low privileges to supply a signed executable through a forged IPC response and cause it to load a malicious DLL from a user-writable temporary directory. Successful exploitation results in arbitrary code execution with NT AUTHORITY\SYSTEM privileges.
