How to Fix CVE-2020-2210

To remediate this vulnerability, upgrade all affected StashBranchParameter 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:StashBranchParameter fixed: Latest secure release
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>StashBranchParameter</artifactId>
    <version>Latest secure release</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-2020-2210, 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 StashBranchParameter in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-319: Cleartext Transmission of Sensitive Information, where the product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors. In StashBranchParameter, 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

Stash Branch Parameter Plugin stores Stash API passwords in its global configuration file `org.jenkinsci.plugins.StashBranchParameter.StashBranchParameterDefinition.xml` on the Jenkins controller as part of its configuration. While the password is stored encrypted on disk, it is transmitted in plain text as part of the configuration form by Stash Branch Parameter Plugin 0.3.0 and earlier. This can result in exposure of the password through browser extensions, cross-site scripting vulnerabilities, and similar situations. This only affects Jenkins before 2.236, including 2.235.x LTS, as Jenkins 2.236 introduces a security hardening that transparently encrypts and decrypts data used for a Jenkins password form field.
