Descriptions

Improper verification of cryptographic signature during installation of a VPN driver via the TeamViewer_service.exe component of TeamViewer Remote Clients prior version 15.58.4 for Windows allows an attacker with local unprivileged access on a Windows system to elevate their privileges and install drivers.

This vulnerability allows local attackers to escalate privileges on affected installations of TeamViewer. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the TeamViewer service, which listens on TCP port 5939 by default. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
