CVE-2023-53877Public exploitNetwork attack vector

Database data theft via pickup_id SQL injection

Published Dec 15, 2025 · Updated Dec 15, 2025

SQL injection in PHPJabbers Bus Reservation System 1.1 allows remote attackers to read database data through the pickup_id parameter. The pjActionGetLocations endpoint sends the GET pickup_id value to MySQL without neutralizing SQL syntax, so injected expressions execute as query logic. No authentication or user interaction is required, and successful exploitation exposes database information.
