Authenticated data disclosure via external XML entities
Published Mar 30, 2021 · Updated Sep 17, 2024
XXE in IBM Jazz Foundation products allows remote authenticated users to read sensitive data or consume server memory through crafted XML. The affected XML-processing locus resolves attacker-supplied external entities; IBM has not published the parser, endpoint, or request format. Low-privileged access and no user interaction are required; exploitation discloses server-accessible data or degrades service through memory consumption.
