How to Fix CVE-2025-3984

To remediate this vulnerability, upgrade all affected Cas management webapp support 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.apereo.cas:cas-management-webapp-support fixed: Latest secure release 
<dependency>
    <groupId>org.apereo.cas</groupId>
    <artifactId>cas-management-webapp-support</artifactId>
    <version>Latest secure release</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.apereo.cas

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-3984, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apereo.cas

Analyze the terminal output to locate any version of Cas management webapp support in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apereo.cas 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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Cas management webapp support, 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

A vulnerability was found in Apereo CAS 5.2.6 and classified as critical. Affected by this issue is the function saveService of the file cas-5.2.6\webapp-mgmt\cas-management-webapp-support\src\main\java\org\apereo\cas\mgmt\services\web\RegisteredServiceSimpleFormController.java of the component Groovy Code Handler. The manipulation leads to code injection. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
