CVE-2024-40625
Java vulnerability analysis and mitigation

Overview

GeoServer, an open source server for sharing and editing geospatial data, was found to contain a Server-Side Request Forgery (SSRF) vulnerability identified as CVE-2024-40625. The vulnerability exists in the Coverage REST API endpoint /workspaces/{workspaceName}/coveragestores/{storeName}/{method}.{format}, which allows attackers to upload files via URL without proper restrictions. This security issue was fixed in GeoServer version 2.26.0 (GitHub Advisory).

Technical details

The vulnerability stems from insufficient URL validation in the Coverage REST API. Specifically, when the {method} parameter is set to 'url', the API fails to implement proper URL checks through the URLCheckers.confirm(fileURL) mechanism. The vulnerability has been assigned a CVSS v3.1 base score of 5.5 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:L, indicating network accessibility, low attack complexity, high privileges required, no user interaction needed, unchanged scope, high confidentiality impact, no integrity impact, and low availability impact (GitHub Advisory).

Impact

The vulnerability presents an opportunity for Server-Side Request Forgery (SSRF), which could potentially allow attackers to make unauthorized requests from the server. The CVSS metrics indicate a high impact on confidentiality and low impact on availability, with no impact on integrity (GitHub Advisory).

Mitigation and workarounds

Users should upgrade to GeoServer version 2.26.0 or later, which contains the fix for this vulnerability. The fix implements proper URL validation checks through the URLCheckers.confirm(fileURL) mechanism (GitHub Advisory).
