CVE-2022-38111Network attack vector

SYSTEM code execution via BytesToMessage deserialization

Published Feb 15, 2023 · Updated Mar 19, 2025

Deserialization in SolarWinds Platform 2022.4.1 and earlier allows remote authenticated users to execute arbitrary commands. The BytesToMessage function fails to validate user-supplied data before deserializing it. Orion administrator access to the Web Console is required, and successful exploitation runs code in the SYSTEM context.
