How to Fix CVE-2022-30951

To remediate this vulnerability, upgrade all affected Windows slaves 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:windows-slaves fixed: 1.8.1 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>windows-slaves</artifactId>
    <version>1.8.1</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-2022-30951, 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 Windows slaves in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.8.1), 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 Windows slaves, 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

WMI Windows Agents Plugin 1.8 and earlier includes the Windows Remote Command library. It provides a general-purpose remote command execution capability that Jenkins uses to check if Java is available, and if not, to install it. This library has a buffer overflow vulnerability that may allow users able to connect to a named pipe to execute commands on the Windows agent machine. Additionally, while the processes are started as the user who connects to the named pipe, no access control takes place, potentially allowing users to start processes even if they’re not allowed to log in. WMI Windows Agents Plugin 1.8.1 no longer includes the Windows Remote Command library. A Java runtime is expected to be available on agent machines and WMI Windows Agents Plugin 1.8.1 does not install a JDK automatically otherwise.
