How to Fix CVE-2024-23643

To remediate this vulnerability, upgrade all affected Gs gwc rest dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.geoserver:gs-gwc-rest fixed: 2.23.2 
<dependency>
    <groupId>org.geoserver</groupId>
    <artifactId>gs-gwc-rest</artifactId>
    <version>2.23.2</version>
</dependency>
org.geoserver:gs-gwc-rest fixed: 2.24.1 
<dependency>
    <groupId>org.geoserver</groupId>
    <artifactId>gs-gwc-rest</artifactId>
    <version>2.24.1</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.geoserver

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-23643, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.geoserver

Analyze the terminal output to locate any version of Gs gwc rest in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.23.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.geoserver command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Gs gwc rest, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary A stored cross-site scripting (XSS) vulnerability exists that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in the GeoServer catalog that will execute in the context of another administrator’s browser when viewed in the GWC Seed Form. Access to the GWC Seed Form is limited to full administrators by default and granting non-administrators access to this endpoint is not recommended. ### Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ ### PoC _Complete instructions, including specific configuration details, to reproduce the vulnerability._ ### Impact If an attacker can control a script that is executed in the victim's browser, then they can typically fully compromise that user. Amongst other things, the attacker can: 1 .Perform any action within the application that the user can perform. 2. View any information that the user is able to view. 3. Modify any information that the user is able to modify. 4. Initiate interactions with other application users, including malicious attacks, that will appear to originate from the initial victim user. ### References https://github.com/GeoWebCache/geowebcache/issues/1172 https://github.com/GeoWebCache/geowebcache/pull/1174
