How to Fix CVE-2022-20613

To remediate this vulnerability, upgrade all affected Mailer 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:mailer fixed: 408.vd726a 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>mailer</artifactId>
    <version>408.vd726a</version>
</dependency>
org.jenkins-ci.plugins:mailer fixed: 1.34.2 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>mailer</artifactId>
    <version>1.34.2</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-2022-20613, 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 Mailer in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 408.vd726a), 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Mailer, 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 Mailer Plugin prior to 408.vd726a_1130320 and 1.34.2 does not perform a permission check in a method implementing form validation. This allows attackers with Overall/Read access to use the DNS used by the Jenkins instance to resolve an attacker-specified hostname. Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. Mailer Plugin 408.vd726a_1130320 and 1.34.2 require POST requests and Overall/Administer permission for the affected form validation method.
