In versions 1.0.0 and above, prior to 4.14.5, a heap buffer overflow in wazuh-analysisd allows an unauthenticated remote attacker to crash the Wazuh manager&#8217;s analysis engine, causing complete loss of SIEM alert processing. The attack exploits the default configuration shipped in the official wazuh\/wazuh-docker deployment with default configuration. An attacker can enroll with authd without a password to obtain a valid agent ID and encryption key, connect to remoted over the Wazuh agent protocol, and inject rootcheck events containing \u00a0{key: value}\u00a0 patterns longer than 30 bytes that trigger a sprintf\u00a0overflow of a 30-byte buffer in W_JSON_ParseRootcheck, corrupting the heap and crashing wazuh-analysisd so that all alert processing silently stops while the dashboard and API keep showing stale data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wazuh is a free and open source platform used for threat prevention, detection, and response.
