**Name of the Vulnerable Software and Affected Versions** AXESS ACS (Auto Configuration Server) versions prior to 5.2.0 **Description** The issue is related to unsanitized user input in the TR069 API, which allows remote unauthenticated attackers to cause a permanent Denial of Service via crafted TR069 requests on TCP port 9675 or 7547. Rebooting does not resolve the permanent Denial of Service. **Recommendations** For AXESS ACS (Auto Configuration Server) versions prior to 5.2.0, as a temporary workaround, consider disabling the TR069 API until a patch is available. Restrict access to the TR069 API on TCP port 9675 or 7547 to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
