CVE-2024-28198Network attack vector

File disclosure and SSRF via unsafe SVG parsing

Published Mar 11, 2024 · Updated Aug 2, 2024

XXE injection in OpenOlat before 18.1.6 allows remote authenticated users to read server files and issue server-side requests. The DrawioServiceImpl.getXmlContent method parses uploaded SVG input with a default DocumentBuilderFactory that permits external entities. Reaching it requires low-privileged access, user interaction, the Draw.io integration, and the REST API; file reads run with service-account access, while SSRF reaches resources visible to the server.
