How to Fix CVE-2024-47806

To remediate this vulnerability, upgrade all affected Oic auth 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.jenkins-ci.plugins:oic-auth fixed: 4.355.v3a 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>oic-auth</artifactId>
    <version>4.355.v3a</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.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-47806, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkins-ci.plugins

Analyze the terminal output to locate any version of Oic auth in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.355.v3a), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.plugins 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Oic auth, 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

Jenkins OpenId Connect Authentication Plugin 4.354.v321ce67a_1de8 and earlier does not check the `aud` (Audience) claim of an ID Token during its authentication flow, a value to verify the token is issued for the correct client. This vulnerability may allow attackers to subvert the authentication flow, potentially gaining administrator access to Jenkins. OpenId Connect Authentication Plugin 4.355.v3a_fb_fca_b_96d4 checks the `aud` (Audience) claim of an ID Token during its authentication flow.
