CVE-2026-40455
SQL Injection in LMS
Description
An SQL Injection vulnerability exists in LMS (LAN Management System) before commit 4cb30a7 within the "tarifflist.php" module due to insufficient sanitization of the POST "tg[]" parameter. The application directly concatenates user-supplied array values into an SQL query using "implode()", allowing authenticated attackers to perform Error-Based SQL injection and extract sensitive database information.
