CVE-2023-4166Public exploitNetwork attack vector

SQL injection via unescaped DELETE_STR parameter

Published Aug 5, 2023 · Updated Oct 15, 2024

SQL injection in Tongda OA before 11.10 allows remote attackers to read or alter database data via crafted DELETE_STR requests. The general/system/seal_manage/dianju/delete_log.php handler uses DELETE_STR in SQL construction without adequate input separation, permitting injected clauses. Exploitation requires network access to the OA web service, and the resulting disclosure or modification is bounded by database permissions.
