CVE-2022-47894Network attack vector

Information disclosure via unsafe XML response parsing

Published Apr 9, 2024 · Updated Feb 13, 2025

XXE in the SAP interpreter in Apache Zeppelin 0.8.0 through 0.10.1 allows remote attackers to read server-accessible data. UniverseClient parses XML responses from the configured SAP server with a default DocumentBuilderFactory that permits external DTD and entity resolution. Exploitation requires Zeppelin to connect the interpreter to an attacker-controlled SAP endpoint, and the reported impact is limited to confidentiality.
