How to Fix CVE-2023-37946

To remediate this vulnerability, upgrade all affected Openshift login 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.openshift.jenkins:openshift-login fixed: 1.1.0.230.v5d7030b 
<dependency>
    <groupId>org.openshift.jenkins</groupId>
    <artifactId>openshift-login</artifactId>
    <version>1.1.0.230.v5d7030b</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.openshift.jenkins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-37946, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.openshift.jenkins

Analyze the terminal output to locate any version of Openshift login in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0.230.v5d7030b), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.openshift.jenkins 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-384: Session Fixation, where authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. In Openshift login, 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 OpenShift Login Plugin 1.1.0.227.v27e08dfb_1a_20 and earlier does not invalidate the existing session on login. This allows attackers to use social engineering techniques to gain administrator access to Jenkins. OpenShift Login Plugin 1.1.0.230.v5d7030b_f5432 invalidates the existing session on login.
