CVE-2025-62785

Wazuh is a free and open source platform used for threat prevention, detection, and response. fillData() implementation does not check whether value is NULL or not before calling os_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 4.10.2.

Summary		(es) Wazuh es una plataforma de código abierto y gratuita utilizada para la prevención, detección y respuesta ante amenazas. La implementación de fillData() no verifica si el valor es NULL o no antes de llamar a os_strdup() sobre él. Un agente comprometido puede causar un fallo de analysisd enviando 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 está corregida en 4.10.2.
