How to Fix CVE-2022-34175

To remediate this vulnerability, upgrade all affected Jenkins core 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.main:jenkins-core fixed: 2.356 
<dependency>
    <groupId>org.jenkins-ci.main</groupId>
    <artifactId>jenkins-core</artifactId>
    <version>2.356</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.main

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-34175, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Jenkins core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.356), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.main 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-693: Protection Mechanism Failure, where the product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. In Jenkins core, 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 uses the Stapler web framework to render its UI views. These views are frequently composed of several view fragments, enabling plugins to extend existing views with more content. Before [SECURITY-534](https://www.jenkins.io/security/advisory/2019-07-17/#SECURITY-534) was fixed in Jenkins 2.186 and LTS 2.176.2, attackers could in some cases directly access a view fragment containing sensitive information, bypassing any permission checks in the corresponding view. In Jenkins 2.335 through 2.355 (both inclusive), the protection added for SECURITY-534 is disabled for some views. As a result, attackers could in very limited cases directly access a view fragment containing sensitive information, bypassing any permission checks in the corresponding view. As of publication, the Jenkins security team is unaware of any vulnerable view fragment across the Jenkins plugin ecosystem. Jenkins 2.356 restores the protection for affected views. No Jenkins LTS release is affected by this issue, as it was not present in Jenkins 2.332.x and fixed in the 2.346.x line before 2.346.1.
