CVE-2025-27138Public exploitNetwork attack vector

Unauthenticated endpoint access via path traversal

Published Mar 13, 2025 · Updated Mar 13, 2025

Authentication bypass in FIT2CLOUD DataEase before 2.10.6 allows remote attackers to reach protected interfaces through a crafted URL. TokenFilter passes request.getRequestURI() to WhitelistUtils.match(), whose invalidUrl() filtering accepts an encoded dot-dot segment after a whitelisted prefix. Exploitation requires a configured servlet context path; the published reproduction reaches the user-information endpoint without token verification.
