How to Fix CVE-2022-36896

To remediate this vulnerability, upgrade all affected Compuware scm downloader dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.compuware.jenkins:compuware-scm-downloader fixed: 2.0.13 
<dependency>
    <groupId>com.compuware.jenkins</groupId>
    <artifactId>compuware-scm-downloader</artifactId>
    <version>2.0.13</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=com.compuware.jenkins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-36896, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.compuware.jenkins

Analyze the terminal output to locate any version of Compuware scm downloader in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.13), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.compuware.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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Compuware scm downloader, 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

BMC Compuware Source Code Download for Endevor, PDS, and ISPW Plugin 2.0.12 and earlier does not perform permission checks in several HTTP endpoints. This allows attackers with Overall/Read permission to enumerate hosts and ports of Compuware configurations and credentials IDs of credentials stored in Jenkins. Those credentials IDs can be used as part of an attack to capture the credentials using another vulnerability. BMC Compuware Source Code Download for Endevor, PDS, and ISPW Plugin 2.0.13 requires the appropriate permissions to enumerate hosts and ports of Compuware configurations and credentials IDs.
