CVE-2022-38114Network attack vector

Cross-site scripting via POST request desynchronization

Published Nov 23, 2022 · Updated Apr 25, 2025

HTTP request smuggling in SolarWinds Security Event Manager before 2022.4 allows remote attackers to inject script via crafted POST requests. The web server mishandles the declared Content-Length and loses request-boundary synchronization when processing POST data. Successful script execution requires user interaction and is limited to reading or altering data in the victim's browser context.
