TeamViewer Exposure of Sensitive Information

high Nessus Plugin ID 135706

Language:

Synopsis

The remote Windows host is missing a security-related update.

Description

The version of TeamViewer installed on the remote Windows host upto 13.1.1548 stores a password in Unicode format within TeamViewer.exe process memory between '[00 88]' and '[00 00 00]' delimiters, which might make it easier for attackers to obtain sensitive information by leveraging an unattended workstation on which TeamViewer has disconnected but remains running.

Solution

Upgrade for Teamviewer 13, upgrade to 13.2.5287 or later. Alternatively, apply the workarounds outlined in the vendor advisory.
