How to Fix CVE-2020-2125

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

ru.yandex.jenkins.plugins.debuilder:debian-package-builder fixed: Latest secure release
<dependency>
    <groupId>ru.yandex.jenkins.plugins.debuilder</groupId>
    <artifactId>debian-package-builder</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=ru.yandex.jenkins.plugins.debuilder

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-2125, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=ru.yandex.jenkins.plugins.debuilder

Analyze the terminal output to locate any version of Debian package builder 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=ru.yandex.jenkins.plugins.debuilder 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-522: Insufficiently Protected Credentials, where the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. In Debian package builder, 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

debian-package-builder Plugin 1.6.11 and earlier stores a GPG passphrase unencrypted in its global configuration file `ru.yandex.jenkins.plugins.debuilder.DebianPackageBuilder.xml` on the Jenkins controller. This credential can be viewed by users with access to the Jenkins controller file system.
