GeoNetwork is a catalog application to manage spatially referenced resources. Prior to 4.2.17 and 4.4.12, POST /api/tools/ogc/sld accepted a caller-supplied WMS server URL and performed a server-side HTTP GET without destination validation. An anonymous attacker could make the GeoNetwork server send requests to internal hosts that are not publicly reachable. When the outbound response was XML, the endpoint could store and return the fetched body, making the request forgery non-blind and enabling internal data disclosure, authorization bypass, and network reconnaissance. This issue is fixed in versions 4.2.17 and 4.4.12.

### Summary An unauthenticated server-side request forgery vulnerability lets any anonymous user make the GeoNetwork server issue arbitrary outbound HTTP requests. This gives an external attacker a position inside the server's network, making it possible to make internal requests no matter if the response is XML-type or not. The SLD tooling endpoint `POST /api/tools/ogc/sld` takes a caller-supplied **WMS server URL** and performs a **server-side HTTP GET** to it, with no validation. The fetched body can also be stored and downloaded if the output of the outbound request is in XML format, making the SSRF non-blind. ### Impact Any unauthenticated user can make the server send arbitrary HTTP requests to internal hosts it would never expose publicly, and read the responses back if the request responses are XML. This enables internal data disclosure, for example, configuration files that return as XML, authorization bypass, and reconnaissance of the internal network all from an anonymous position. ### Resolution Patched releases: * 4.4.12 * 4.2.17 ### Resources * https://github.com/geonetwork/core-geonetwork/pull/9343
