Unauthenticated file disclosure via SVG entity expansion
Published Sep 23, 2024 · Updated Sep 23, 2024
XXE in DataEase before 2.10.1 allows remote attackers to read server files and probe internal hosts through crafted SVG uploads. The static-resource upload path resolves external DTDs and parameter entities in attacker-controlled SVG XML, causing server-side HTTP requests and file expansion. No authentication or user interaction is required, and out-of-band callbacks can disclose local file contents or reveal reachable intranet services.
