Authenticated disclosure via exposed SWIS community strings

Published Apr 25, 2023 · Updated Feb 4, 2025

Information disclosure in SolarWinds Platform 2023.1 and earlier allows remote authenticated users to read sensitive community strings. The Orion.WebCommunityStrings SWIS schema object returns stored values to authenticated Platform users without limiting access to appropriately authorized roles. A valid Platform account and network access to SWIS are required; disclosure is limited to information held by that schema object.
