Descriptions

The Collector Service in SolarWinds Orion Platform before 2020.2.4 uses MSMQ (Microsoft Message Queue) and doesn't set permissions on its private queues. As a result, remote unauthenticated clients can send messages to TCP port 1801 that the Collector Service will process. Additionally, upon processing of such messages, the service deserializes them in insecure manner, allowing remote arbitrary code execution as LocalSystem.

El Collector Service en SolarWinds Orion Platform versiones anteriores a 2020.2.4 usa MSMQ (Microsoft Message Queue) y no establece permisos en sus queues privadas. Como resultado, unos clientes no autenticados remotos pueden enviar mensajes hacia el puerto TCP 1801 que el Collector Service procesará. Adicionalmente, al procesar dichos mensajes, el servicio los deserializa de una manera no segura, permitiendo una ejecución de código remota arbitraria como LocalSystem
