CVE-2023-29517Public exploitNetwork attack vector

Unauthenticated file disclosure and SSRF via office viewer

Published Apr 18, 2023 · Updated Feb 5, 2025

Information disclosure in XWiki Platform allows remote attackers to read host files through the office viewer macro. The office viewer accepts attacker-controlled fetch input without restricting local-file or internal-network destinations. No authentication or user interaction is required; reachability depends on a connected office server, and exposure is bounded by the servlet-engine account's file and network access.
