CVE-2020-22165Public exploitNetwork attack vector

Database information disclosure via direct username insertion

Published Jun 22, 2021 · Updated Aug 4, 2024

SQL injection in PHPGurukul Hospital Management System 4.0 allows remote attackers to read database information through user-login.php. Line 7 inserts the username POST value directly into a database query, allowing crafted SQL to alter query logic and extract values through response delays. The login endpoint requires no authentication, and the demonstrated time-based oracle discloses database values without changing records or interrupting service.
