TeamViewer Permissions Vulnerability (macOS)

Medium Nessus Plugin ID 105110

Synopsis

The remote macOS or Mac OS X host contains an application that is affected by a permissions vulnerability.

Description

According to its version number, the TeamViewer install on the remote macOS or Mac OS X host is a version prior to 11.0.73955, 12.0.82953, or 13.0.5640.
It is, therefore, affected by a permissions vulnerability than can result in unauthorized remote control.

During an authenticated connection it may be possible for an attacker to control the mouse without regard for the server's current control setting. This can be exploited from both the viewer and presenter roles, enabling the viewer to control the presenters mouse or enabling the 'switch sides' feature without requiring the client to agree.

Solution

Upgrade to TeamViewer 11.0.73955 / 12.0.82953 / 13.0.5640 or later.
