CVE-2022-24853Public exploitNetwork attack vector

NTLM hash disclosure via crafted GeoJSON URL

Published Apr 14, 2022 · Updated Apr 22, 2025

Server-side request forgery in affected Metabase releases allows remote attackers to capture a Windows server account's NTLM hash. The /api/geojson proxy passes a crafted jar:file UNC URL to Java's URL handler after its scheme validation rejects ordinary file URLs, initiating SMB authentication. Exploitation requires Metabase to run on Windows and an authenticated administrator to open the crafted link; the disclosed hash enables NTLM relay or offline cracking.
