In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These tools can potentially detect and block malicious MQTT messages, reducing the risk of exploitation. It&#8217;s also advisable to monitor network traffic for any unusual activity, particularly involving MQTT messages.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview CVE-2025-24003 is a highly severe vulnerability that allows an unauthenticated remote attacker to exploit charging stations that comply with the German Calibration Law (Eichrecht).
