Descriptions

Fleet is an open source osquery manager. In Fleet before version 3.7.0 a malicious actor with a valid node key can send a badly formatted request that causes the Fleet server to exit, resulting in denial of service. This is possible only while a live query is currently ongoing. We believe the impact of this vulnerability to be low given the requirement that the actor has a valid node key. There is no information disclosure, privilege escalation, or code execution. The issue is fixed in Fleet 3.7.0.

Fleet es un administrador osquery de código abierto. En Fleet versiones anteriores a 3.7.0, un actor malicioso con una clave de nodo válida puede enviar una petición mal formateada que hace que el servidor Fleet salga, lo que resulta en la denegación del servicio. Esto solo es posible mientras se presenta una consulta en vivo en curso. Creemos que el impacto de esta vulnerabilidad es bajo el requerimiento dado de que el actor tenga una clave de nodo válida. No existe una divulgación de información, escalada de privilegios ni ejecución de código. El problema es corregido en Fleet versión 3.7.0
