Authenticated database disclosure via dashboard SQL injection
Published May 27, 2026 · Updated May 27, 2026
SQL injection in myREX24 V2 and mbCONNECT24-family portals 2.20.0 and earlier allows remote authenticated users to read the database. The dash_layout.php saveDashboardLayout function places attacker-controlled layout data into an SQL INSERT command without neutralizing SQL syntax. A low-privileged portal account is required; exploitation can disclose the entire database and insert rows into a noncritical table, without reported availability impact.
