How to Fix CVE-2022-23106

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

io.jenkins:configuration-as-code fixed: 1.55.1 
<dependency>
    <groupId>io.jenkins</groupId>

</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=io.jenkins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-23106, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins

Analyze the terminal output to locate any version of Configuration as code in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.55.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins 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-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. In Configuration as code, 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 Configuration as Code Plugin prior to 1.55.1, 1.54.1, 1.53.1, and 1.47.1 does not use a constant-time comparison when checking whether two authentication tokens are equal. This could potentially allow attackers to use statistical methods to obtain a valid authentication token. Configuration as Code Plugin 1.55.1, 1.54.1, 1.53.1, and 1.47.1 now uses a constant-time comparison when validating authentication tokens.
