CVE-2024-28138Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized data parameter

Published Dec 10, 2024 · Updated Nov 3, 2025

OS command injection in Image Access Scan2Net before 7.40 allows remote attackers to execute system commands through its web interface. The msg_events.php script passes the HTTP GET data parameter without proper sanitization, so a semicolon can append attacker-chosen commands. No authentication is required; network access to the device is enough, and injected commands run with the privileges of the www-data user.
