CVE-2022-29265Network attack vector

File disclosure via unrestricted external XML entities

Published Apr 30, 2022 · Updated Aug 3, 2024

XXE in Apache NiFi 0.0.1 through 1.16.0 allows remote attackers to read files through malicious XML processed by affected components. The Standard Content Viewer resolves external entity references while formatting XML, and EvaluateXPath, EvaluateXQuery, and ValidateXml do so under default property values. Exposure requires a flow that routes attacker-controlled XML to those processors or use of the viewer; external entities can read local data or trigger outbound requests.
