Wago · Wagoapprtu · CVE-2023-5188
**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.
