CVE-2023-29598Public exploitNetwork attack vector

SQL injection via unfiltered form-array keys

Published Apr 13, 2023 · Updated Feb 7, 2025

SQL injection in lmxcms 1.4.1 allows remote attackers to execute arbitrary SQL through a crafted front-page request to index.php. The message handler filters form-array values but passes attacker-controlled keys into addDB(), which concatenates them into an INSERT statement. No authenticated session or user interaction is required, and injected SQL runs with the web application's database permissions.
