CVE-2023-6898Public exploitNetwork attack vector

Database compromise via concatenated id parameter

Published Dec 17, 2023 · Updated May 7, 2025

SQL injection in SourceCodester Best Courier Management System 1.0 allows remote attackers to compromise its database via a crafted id parameter. The manage_user.php handler concatenates the user-controlled id value directly into an SQL statement instead of binding it as data. The published proof of concept sends a single unauthenticated GET request and demonstrates a time-delay oracle, enabling database reads and writes through SQL execution.
