**Name of the Vulnerable Software and Affected Versions** WagoAppRTU versions prior to 1.4.6.0 **Description** The issue is related to the MMS Interpreter of WagoAppRTU, which is used by the WAGO Telecontrol Configurator. It is vulnerable to malformed packets, allowing a remote unauthenticated attacker to send specifically crafted packets that lead to a denial-of-service condition until the restart of the affected device. The vulnerability is associated with errors in processing input data. **Recommendations** For versions prior to 1.4.6.0, update to version 1.4.6.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the MMS Interpreter to minimize the risk of exploitation.
