APP: SolarWinds Orion Platform MSMQ Insecure Deserialization

This signature detects attempts to exploit a known vulnerability against SolarWinds Orion Platform MSMQ. A successful attack can lead to arbitrary code execution with SYSTEM context.

Extended Description

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.
