CVE-2023-31938Public exploitNetwork attack vector

Authenticated code execution via unsanitized emp_id query

Published Aug 17, 2023 · Updated Oct 7, 2024

SQL injection in Online Travel Agency System 1.0 allows remote authenticated users to execute arbitrary code through emp_id. employee_detail.php inserts the GET value directly into a quoted SELECT statement passed to mysqli_query, without validation or parameterization. Access to the administrative employee-detail endpoint and a valid session are required; crafted predicates can alter database queries and lead to code execution.
