How to Fix CVE-2021-21632

To remediate this vulnerability, upgrade all affected Dependency track 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:dependency-track fixed: 3.1.1 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>dependency-track</artifactId>
    <version>3.1.1</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-2021-21632, 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 Dependency track in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.1), 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-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 Dependency track, 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 OWASP Dependency-Track Plugin 3.1.0 and earlier does not perform permission checks in several HTTP endpoints. This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing \"Secret text\" credentials stored in Jenkins. If no credentials ID is specified, the globally configured credential is used, if set up, and can likewise be captured. Jenkins OWASP Dependency-Track Plugin 3.1.1 requires appropriate permissions for the affected HTTP endpoints.
