Java vulnerability analysis and mitigation

Overview

GeoServer's GeoWebCache component has a security vulnerability (CVE-2024-38524) that exposes sensitive server information through its home page. The vulnerability affects GeoServer versions 2.26.0 to 2.26.2 and versions prior to 2.25.6. The issue was discovered in January 2025 and involves the org.geowebcache.GeoWebCacheDispatcher.handleFrontPage() method, which lacks proper security controls for hiding sensitive information from unauthorized users (GitHub Advisory).

Technical details

The vulnerability exists in the GeoWebCache's front page implementation where org.geowebcache.GeoWebCacheDispatcher.handleFrontPage(HttpServletRequest, HttpServletResponse) method lacks proper security checks for displaying sensitive information. While there is a hidden system property to hide storage locations, it defaults to showing the locations. The vulnerability has been assigned a CVSS v3.1 base score of 5.3 (Moderate) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating it is network-accessible with low attack complexity and requires no privileges or user interaction (GitHub Advisory).

Impact

The vulnerability exposes sensitive server information including version numbers, revision information, configuration file locations, and storage locations. This can reveal system details such as temporary directory locations and operating system type (Windows vs. others). Additionally, it discloses the approximate server start time and basic GeoWebCache usage information. This information could be valuable to attackers for targeting specific versions or configurations (GitHub Advisory).

Mitigation and workarounds

The vulnerability has been fixed in GeoServer versions 2.26.2 and 2.25.6. Users should upgrade to these patched versions to address the security issue. The fix implements proper security controls to hide sensitive information from unauthorized users, making it visible only to authenticated administrators (GitHub Advisory).

Community reactions

The vulnerability was actively discussed and addressed by the GeoServer community, with multiple pull requests and discussions taking place on GitHub. The fix was implemented through collaborative effort between community members, with careful consideration given to both standalone and embedded GeoWebCache deployments (GeoWebCache PR, GeoServer PR).
