EXPLOIT

DataEase is an open source business intelligence and data visualization tool. Prior to version 2.10.10, secret verification does not take effect successfully, so a user can use any secret to forge a JWT token. The vulnerability has been fixed in v2.10.10. No known workarounds are available.

path /de2api/user/info↗

• → Forged JWT token sent via X-DE-TOKEN header to /de2api/user/info; a successful exploit returns HTTP 400 with response headers containing both 'de-gateway-flag' and 'hmacsha256', and body containing 'getWriter() has already been called' ↗
• → Unauthenticated baseline check: GET /de2api/user/info returns HTTP 401 with body containing 'token is empty', confirming a vulnerable DataEase instance before attempting JWT bypass ↗
• → Shodan/FOFA fingerprint for exposed DataEase instances: search for HTTP title 'DataEase' ↗
• → Response header 'x-de-execute-version' can be extracted to confirm DataEase version on exploited instances ↗

• · The forged JWT uses HS256 with uid=1 (admin) and a far-future expiry (exp=9999999999). The vulnerability is that DataEase versions prior to 2.10.10 do not properly validate the JWT secret, so ANY secret produces an accepted token. ↗
• · No known workarounds exist; the only remediation is upgrading to DataEase v2.10.10 or later. ↗
