Database disclosure via DELETE_STR blind SQL injection
Published Aug 5, 2023 · Updated Oct 10, 2024
SQL injection in Tongda OA before 11.10 allows remote authenticated users to read database contents through crafted DELETE_STR input. The delete_seal.php endpoint accepts SQL expressions in DELETE_STR that alter query execution and expose values through response timing. Exploitation requires low-privileged access from an adjacent network; the published proof of concept extracts database characters with costly Cartesian-product delays.
