How to Fix CVE-2022-34179

To remediate this vulnerability, upgrade all affected Embeddable build status 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:embeddable-build-status fixed: 2.0.4 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>embeddable-build-status</artifactId>
    <version>2.0.4</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-2022-34179, 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 Embeddable build status in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.4), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Embeddable build status, 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 Embeddable Build Status Plugin 2.0.3 and earlier allows specifying a `style` query parameter that is used to choose a different SVG image style without restricting possible values, resulting in a relative path traversal vulnerability that allows attackers without Overall/Read permission to specify paths to other SVG images on the Jenkins controller file system. Embeddable Build Status Plugin 2.0.4 restricts the `style` query parameter to one of the three legal values.
