Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 36.4%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
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.
