CVE-2026-2695: CWE-20 Improper input validation in TeamViewer DEX (On-Premises)
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.
AI Analysis
Technical Summary
This vulnerability in TeamViewer DEX (On-Premises) is due to improper input validation (CWE-20) that permits command injection by authenticated users with questioner-level privileges. The flaw exists in versions prior to 9.2 and could allow attackers to execute elevated commands on connected devices. The CVSS 3.1 base score is 6.3, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and impacts on confidentiality, integrity, and availability. No patch or official remediation level has been disclosed yet.
Potential Impact
An authenticated user with questioner privileges can exploit this vulnerability to inject and execute elevated commands on devices connected to the TeamViewer DEX On-Premises platform. This could lead to unauthorized actions affecting confidentiality, integrity, and availability of those devices. However, there are no reports of active exploitation in the wild currently.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict questioner-level access to trusted users only and monitor for unusual command activity related to the platform.
