SYSTEM command execution via MessageToBytes deserialization
Published Oct 20, 2022 · Updated May 8, 2025
Unsafe deserialization in SolarWinds Platform 2022.3 and earlier allows remote authenticated users to execute arbitrary commands. The MessageToBytes path passes attacker-controlled AMQP type metadata and a serialized payload to SerializationHelper.Deserialize without restricting the target type. Exploitation requires Orion administrator credentials and executes commands as SYSTEM on the main poller.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <=2020.2.6 HF5 and prior versions
- Affected versionversion=unspecified <=2022.3 and prior versions
