**Name of the Vulnerable Software and Affected Versions** Tongda OA 2017 versions up to 11.9 **Description** A critical issue has been found in an unknown functionality of the file general/system/approve center/flow sort/flow/delete.php. The manipulation of the `id/sort parent` argument leads to sql injection. The attack can be launched remotely. **Recommendations** For Tongda OA 2017 versions up to 11.9, upgrade to version 11.10 to address this issue. As a temporary workaround, consider restricting access to the vulnerable file general/system/approve center/flow sort/flow/delete.php until a patch is available.
