**Name of the Vulnerable Software and Affected Versions** Netentsec NS-ASG Application Security Gateway version 6.3 **Description** A critical issue was found in the Netentsec NS-ASG Application Security Gateway, affecting some unknown functionality of the file /admin/list onlineuser.php. The manipulation of the `SessionId` argument leads to SQL injection. The exploit has been disclosed to the public and may be used. **Recommendations** For version 6.3, as a temporary workaround, consider restricting access to the /admin/list onlineuser.php file until a patch is available.
