CVE-2025-62789

Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.11.0, fim_alert() implementation does not check whether the return value of ctime_r is NULL or not before calling strdup() on it. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause analysisd to crash and make it unavailable. This vulnerability is fixed in 4.11.0.

Summary		(es) Wazuh es una plataforma gratuita y de código abierto utilizada para la prevención, detección y respuesta a amenazas. Antes de la versión 4.11.0, la implementación de fim_alert() no verifica si el valor de retorno de ctime_r es NULL o no antes de llamar a strdup() sobre él. Un agente comprometido puede causar un fallo de analysisd al enviar un mensaje especialmente diseñado al gestor de Wazuh. Un atacante que sea capaz de diseñar y enviar un mensaje de agente al gestor de Wazuh puede causar que analysisd falle y lo deje no disponible. Esta vulnerabilidad se corrige en la versión 4.11.0.
