CVE-2022-28140Network attack vector

Controller secret extraction and SSRF via external entities

Published Mar 29, 2022 · Updated Aug 3, 2024

XXE in the XML parser of Jenkins Flaky Test Handler Plugin 1.2.1 and earlier allows remote authenticated users to extract controller secrets. The plugin passes a crafted file to an XML parser that resolves attacker-supplied external entities instead of disabling their resolution. Item/Configure permission is required; entity resolution can read Jenkins controller secrets or send server-side requests.
