Critical · 10.0 Scanner template Public exploit CVE-2025-34073 EUVD-2025-19716GHSA-6655-8f3g-xp52

stamparm/maltrail <=0.54 Remote Command Execution

Published Jul 2, 2025 · Updated May 14, 2026 · Assigned by VulnCheck

Vendor: stamparm Product: maltrail

Description

An unauthenticated command injection vulnerability exists in stamparm/maltrail (Maltrail) versions <=0.54. A remote attacker can execute arbitrary operating system commands via the username parameter in a POST request to the /login endpoint. This occurs due to unsafe handling of user-supplied input passed to subprocess.check_output() in core/http.py, allowing injection of shell metacharacters. Exploitation does not require authentication and commands are executed with the privileges of the Maltrail process.
