CVE-2025-58175: CWE-20: Improper Input Validation in geoserver org.geoserver.web:gs-web-app
GeoServer is an open source server that allows users to share and edit geospatial data. Prior to versions 2.26.4 and 2.27.3, a GeoServer that uses `ENTITY_RESOLUTION_ALLOWLIST` may allow attacker to perform unauthenticated Server-Side Request Forgery (SSRF). This vulnerability requires that GeoServer is set up to use a proxy base URL and the `ENTITY_RESOLUTION_ALLOWLIST` (default since 2.25.0). Versions 2.26.4 and 2.27.3 contain a fix. GeoServer installations are only affected by this vulnerability if they use a proxy base URL that does not contain a URL path or end with a slash. If the proxy base URL does not contain a path, adding a slash to the end of the URL will mitigate this vulnerability.
AI Analysis
Technical Summary
CVE-2025-58175 is an improper input validation vulnerability in GeoServer's gs-web-app component. Specifically, when GeoServer is configured with ENTITY_RESOLUTION_ALLOWLIST (default since 2.25.0) and uses a proxy base URL without a URL path or trailing slash, an attacker may perform unauthenticated SSRF attacks. The vulnerability is fixed in GeoServer versions 2.26.4 and 2.27.3. The issue only affects installations with the described proxy base URL configuration. Adding a trailing slash to the proxy base URL without a path also mitigates the vulnerability.
Potential Impact
Successful exploitation allows unauthenticated attackers to perform SSRF, potentially leading to unauthorized access to internal resources or services. The CVSS score of 6.5 (medium severity) reflects a network attack vector with high complexity and no privileges required, impacting confidentiality with limited impact on availability and no integrity impact.
Mitigation Recommendations
Upgrade GeoServer to version 2.26.4 or 2.27.3 or later where the vulnerability is fixed. If upgrading is not immediately possible, ensure that the proxy base URL configuration includes a trailing slash if it does not contain a URL path, as this mitigates the vulnerability. No other mitigation steps are specified.
