Descriptions

Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 4.4.0 and prior to version 4.9.1, an unsafe deserialization vulnerability allows for remote code execution on Wazuh servers. DistributedAPI parameters are a serialized as JSON and deserialized using `as_wazuh_object` (in `framework/wazuh/core/cluster/common.py`). If an attacker manages to inject an unsanitized dictionary in DAPI request/response, they can forge an unhandled exception (`__unhandled_exc__`) to evaluate arbitrary python code. The vulnerability can be triggered by anybody with API access (compromised dashboard or Wazuh servers in the cluster) or, in certain configurations, even by a compromised agent. Version 4.9.1 contains a fix.

Wazuh es una plataforma gratuita y de código abierto que se utiliza para la prevención, detección y respuesta ante amenazas. A partir de la versión 4.4.0 y antes de la versión 4.9.1, una vulnerabilidad de deserialización insegura permite la ejecución remota de código en servidores Wazuh. Los parámetros de DistributedAPI se serializan como JSON y se deserializan utilizando `as_wazuh_object` (en `framework/wazuh/core/cluster/common.py`). Si un atacante logra inyectar un diccionario no depurado en una solicitud/respuesta DAPI, puede falsificar una excepción no controlada (`__unhandled_exc__`) para evaluar código Python arbitrario. La vulnerabilidad puede ser activada por cualquier persona con acceso a la API (panel de control comprometido o servidores Wazuh en el clúster) o, en ciertas configuraciones, incluso por un agente comprometido. La versión 4.9.1 contiene una corrección.

Wazuh versions starting at 4.4.0 and before 4.9.1 suffer from an unsafe deserialization vulnerability that allows for remote code execution.

Wazuh contains a deserialization of untrusted data vulnerability that allows for remote code execution on Wazuh servers.
