Technical ContextAI
The vulnerability stems from improper input validation in a PHP-based web application handling hotel reservations. The root cause is classified as CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses SQL injection as a specific manifestation. The /admin/confirm_reserve.php script directly incorporates user-supplied input (transaction_id parameter) into SQL queries without parameterized statements or prepared statements. This is a classic unsafe query construction pattern where concatenation of untrusted input into SQL strings allows attackers to inject malicious SQL syntax. The affected product is code-projects Simple Online Hotel Reservation System 1.0, likely deployed as a PHP application running on web servers with database backends (MySQL, PostgreSQL, or similar RDBMS).
