Wazuh is a free and open source platform used for threat prevention, detection, and response. Versions 4.0.0 through 4.14.2 have a Remote Code Execution (RCE) vulnerability due to Deserialization of Untrusted Data). All Wazuh deployments using cluster mode (master/worker architecture) and any organization with a compromised worker node (e.g., through initial access, insider threat, or supply chain attack) are impacted. An attacker who gains access to a worker node (through any means) can achieve full RCE on the master node with root privileges. Version 4.14.3 fixes the issue.

Ein Angreifer kann mehrere Schwachstellen in Wazuh ausnutzen, um Sicherheitsvorkehrungen zu umgehen, Root-Rechte zu erlangen, beliebigen Code mit Root-Rechten auszuführen oder einen Denial-of-Service-Zustand herbeizuführen.
