**Name of the Vulnerable Software and Affected Versions** Tongda OA 2017 versions up to 11.9 **Description** A critical issue has been found in Tongda OA 2017, affecting an unknown functionality of the file general/project/proj/delete.php. The manipulation of the `PROJ ID STR` argument leads to sql injection. The exploit has been disclosed to the public and may be used. **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 `delete.php` file until the upgrade is applied. Avoid using the `PROJ ID STR` argument in the affected functionality until the issue is resolved.
