CVE-2019-18196: TeamViewer

Medium severity, CVSS 6.7. EPSS: 0.6% chance of exploitation in the next 30 days.

A DLL side loading vulnerability in the Windows Service in TeamViewer versions up to 11.0.133222 (fixed in 11.0.214397), 12.0.181268 (fixed in 12.0.214399), 13.2.36215 (fixed in 13.2.36216), and 14.6.4835 (fixed in 14.7.1965) on Windows could allow an attacker to perform code execution on a target system via a service restart where the DLL was previously installed with administrative privileges. Exploitation requires that an attacker be able to create a new file in the TeamViewer application directory; directory permissions restrict that by default.

Affected products

• TeamViewer TeamViewer: before 11.0.214397 (fixed in 11.0.214397); from 12.0.0, before 12.0.214399 (fixed in 12.0.214399); from 13.0.0, before 13.2.36216 (fixed in 13.2.36216); from 14.0.0, before 14.7.1965 (fixed in 14.7.1965)
