Administrator authentication bypass via password SQL injection
Published Mar 31, 2022 · Updated Aug 4, 2024
SQL injection in Login.php in Sourcecodester Simple Client Management System 1.0 allows remote attackers to bypass administrator authentication. The login handler fails to neutralize SQL syntax in the password parameter, so a crafted always-true expression changes the authentication query result. No credentials or user interaction are required; successful exploitation grants access to the administrative interface as the admin user.
