Vulnerability from cvelistv5 – Published: 2026-05-13 16:09 – Updated: 2026-05-13 17:45

Title

Lack of Server-side validation in Instruction Input in TeamViewer DEX Platform (On-Premises)

Summary

A command injection vulnerability was discovered in TeamViewer DEX Platform On-Premises (former 1E DEX Platform On-Premises) prior to version 9.2. Improper input validation allows authenticated users with at least questioner privileges to inject commands in specific instructions. Exploitation could lead to execution of elevated commands on devices connected to the platform.

Severity

6.3 (Medium)
