Authenticated SQL injection via club parameter

Published Sep 17, 2023 · Updated Aug 2, 2024

SQL injection in club_validator.php in SourceCodester Simple Membership System 1.0 allows remote authenticated users to manipulate database queries. Public records identify club_validator.php and its club parameter but do not disclose the exact SQL statement or data flow that fails to neutralize the input. Low-privileged application access is sufficient, and successful exploitation permits unauthorized database reads, writes, and service interruption.
