CVE-2025-62791

Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.11.0, DecodeCiscat() implementation does not check the return the value of cJSON_GetObjectItem() for a possible NULL value in case of an error. 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 de código abierto y gratuita utilizada para la prevención, detección y respuesta a amenazas. Antes de la versión 4.11.0, la implementación de DecodeCiscat() no verifica el valor de retorno de cJSON_GetObjectItem() para un posible valor NULL en caso de error. Un agente comprometido puede causar una caída 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 se caiga y lo deje no disponible. Esta vulnerabilidad se corrige en la versión 4.11.0.
