## Overview

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.

## Affected

- `full_client < 15.82`
- `full_client >= 15.64.0 (Legacy Windows 7 & 8) < 15.64.10 (Legacy Windows 7 & 8)`
- `full_client >= 14.7.0 < 14.7.48868`
- `full_client >= 13.2.0 < 13.2.36231`
- `Host < 15.82`
- `Host >= 15.64.0 (Legacy Windows 7 & 8) < 15.64.10 (Legacy Windows 7 & 8)`
- `Host >= 14.7.0 < 14.7.48868`
- `Host >= 13.2.0 < 13.2.36231`

## Remediation

Update to the latest available version.
