CVE-2023-5783Public exploitNetwork attack vector

Authenticated database disclosure via unescaped delete parameters

Published Oct 26, 2023 · Updated Jun 12, 2025

SQL injection in Tongda OA 2017 11.9 and earlier allows remote authenticated users to read database data via crafted id or sort_parent values. The delete.php handler directly splices nonempty id and sort_parent values into an SQL statement, enabling time-based blind queries. Access to the approval-center flow-sorting endpoint is required; successful exploitation can infer arbitrary database information.
