How to Fix CVE-2023-32986

To remediate this vulnerability, upgrade all affected File parameters 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.plugins:file-parameters fixed: 285.287.v4b 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>file-parameters</artifactId>
    <version>285.287.v4b</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=io.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-32986, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugins

Analyze the terminal output to locate any version of File parameters in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 285.287.v4b), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins.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-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In File parameters, 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 File Parameter Plugin 285.v757c5b_67a_c25 and earlier does not restrict the name (and resulting uploaded file name) of Stashed File Parameters. This allows attackers with Item/Configure permission to create or replace arbitrary files on the Jenkins controller file system with attacker-specified content. File Parameter Plugin 285.287.v4b_7b_29d3469d restricts the name (and resulting uploaded file name) of Stashed File Parameters.
