Name of the Vulnerable Software and Affected Versions
GeoNetwork versions prior to 4.2.17
GeoNetwork versions prior to 4.4.12
Description
An unauthenticated server-side request forgery (SSRF) exists where the server performs a server-side HTTP GET request without destination validation. This occurs at the endpoint "/api/tools/ogc/sld" when it processes a caller-supplied WMS server URL. An anonymous attacker can leverage this to force the server to send requests to internal hosts that are not publicly accessible. If the outbound response is in XML format, the endpoint can store and return the fetched body, making the request forgery non-blind. This can lead to internal data disclosure, authorization bypass, and network reconnaissance.
Recommendations
Update to version 4.2.17.
Update to version 4.4.12.
