How to Fix CVE-2024-39459

To remediate this vulnerability, upgrade all affected Plain credentials 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:plain-credentials fixed: 183.va 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>plain-credentials</artifactId>
    <version>183.va</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-2024-39459, 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 Plain credentials in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 183.va), 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 Plain credentials, 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

When creating secret file credentials Plain Credentials Plugin 182.v468b_97b_9dcb_8 and earlier attempts to decrypt the content of the file to check if it constitutes a valid encrypted secret. In rare cases the file content matches the expected format of an encrypted secret, and the file content will be stored unencrypted (only Base64 encoded) on the Jenkins controller file system. These credentials can be viewed by users with access to the Jenkins controller file system (global credentials) or with Item/Extended Read permission (folder-scoped credentials). Plain Credentials Plugin 183.va_de8f1dd5a_2b_ no longer attempts to decrypt the content of the file when creating secret file credentials.
