DataEase < 2.10.4 - Authentication Bypass via Whitelist Path Traversal

id: CVE-2024-56511

info:
  name: DataEase < 2.10.4 - Authentication Bypass via Whitelist Path Traversal
  author: ChrisJr404
  severity: critical
  description: |
    DataEase versions up to and including 2.10.3 contain an authentication bypass in `io.dataease.auth.filter.TokenFilter`. The filter passes the raw, unnormalized request URI to `WhitelistUtils.match()`, which only checks for whitelisted prefixes such as `/geo/`, `/customGeo/`, `/map/`, `/oauth2/`, and `/websocket` without resolving `..` segments. By prepending a whitelisted prefix and traversing back into the configured `server.servlet.context-path`, an attacker bypasses the filter while Tomcat still routes the request to the genuine, protected controller. This collapses the entire `/de2api` surface (user management, datasources, dashboards, exports) into unauthenticated access.
  impact: |
    An unauthenticated attacker can reach every `/de2api` endpoint as if authenticated, exposing user management, datasource configuration, dashboards, and exports. Chained with CVE-2025-32966  (H2 JDBC RCE) the bypass becomes pre-auth remote code execution.
  remediation: |
    Upgrade to DataEase 2.10.4 or later, which normalizes the request path before whitelist matching.
