How to Fix CVE-2020-2178

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

com.parasoft:parasoft-findings fixed: 10.4.4 
<dependency>
    <groupId>com.parasoft</groupId>
    <artifactId>parasoft-findings</artifactId>
    <version>10.4.4</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=com.parasoft

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-2178, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.parasoft

Analyze the terminal output to locate any version of Parasoft findings in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 10.4.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.parasoft 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-611: Improper Restriction of XML External Entity Reference, where the product processes an xml document that can contain xml entities with uris that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. In Parasoft findings, 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

Parasoft Findings Plugin implements a static analysis parser for various Parasoft products and integrates with [Warnings Plugin](https://plugins.jenkins.io/warnings) (10.4.1 and earlier) and [Warnings NG Plugin](https://plugins.jenkins.io/warnings-ng) (10.4.2 and newer). Parasoft Findings Plugin 10.4.3 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows a user able to control the input files for the Parasoft Findings parser to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery. Parasoft Findings Plugin 10.4.4 disables external entity resolution for its XML parser.
