- CWE-732 - Incorrect Permission Assignment for Critical Resource
Summary
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.
