How to Fix CVE-2024-23899

To remediate this vulnerability, upgrade all affected Git server 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:git-server fixed: 99.101.v720e86326c09 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>git-server</artifactId>
    <version>99.101.v720e86326c09</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-2024-23899, 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 Git server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 99.101.v720e86326c09), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Git server, 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 Git server Plugin uses the [args4j](https://github.com/kohsuke/args4j) library to parse command arguments and options on the Jenkins controller when processing Git commands received via SSH. This command parser has a feature that replaces an @ character followed by a file path in an argument with the file’s contents (`expandAtFiles`). This feature is enabled by default and Git server Plugin 99.va_0826a_b_cdfa_d and earlier does not disable it. This allows attackers with Overall/Read permission to read the first two lines of arbitrary files on the Jenkins controller file system using the default character encoding of the Jenkins controller process. See [SECURITY-3314](https://www.jenkins.io/security/advisory/2024-01-24/#SECURITY-3314) for further information about the potential impact of being able to read files on the Jenkins controller, as well as the [limitations for reading binary files](https://www.jenkins.io/security/advisory/2024-01-24/#binary-files-note). Note that for this issue, unlike SECURITY-3314, attackers need Overall/Read permission. ## Fix Description Git server Plugin 99.101.v720e86326c09 disables the command parser feature that replaces an @ character followed by a file path in an argument with the file’s contents for CLI commands. ## Workaround Navigate to Manage Jenkins » Security and ensure that the SSHD Port setting in the SSH Server section is set to Disable. This disables access to Git repositories hosted by Jenkins (and the Jenkins CLI) via SSH.
