How to Fix CVE-2023-37943

To remediate this vulnerability, upgrade all affected Active directory 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:active-directory fixed: 2.30.1 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>active-directory</artifactId>
    <version>2.30.1</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-2023-37943, 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 Active directory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.30.1), 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-311: Missing Encryption of Sensitive Data, where the product does not encrypt sensitive or critical information before storage or transmission. In Active directory, 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 Active Directory Plugin allows testing a new, unsaved configuration by performing a connection test (the button labeled "Test Domain"). Active Directory Plugin 2.30 and earlier ignores the "Require TLS" and "StartTls" options and always performs the connection test to Active directory unencrypted. This allows attackers able to capture network traffic between the Jenkins controller and Active Directory servers to obtain Active Directory credentials. This only affects the connection test. Connections established during the login process are encrypted if the corresponding TLS option is enabled. Active Directory Plugin 2.30.1 considers the "Require TLS" and "StartTls" options for connection tests.
