Vulnerability from fkie_nvd - Published: 2025-12-11 12:16 - Updated: 2026-10-08 10:10
Severity
6.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H
6.7 (Medium) - CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
A privilege escalation vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-SetWorkRate instruction prior V17.1. The improper handling of executable search paths could allow local attackers with write access to a PATH directory on a device to escalate privileges and execute arbitrary code as SYSTEM.
