How to Fix CVE-2021-34079

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

docker-tester fixed: Latest secure release 
npm install docker-tester@Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls docker-tester

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-34079, inspect your project dependencies using npm:

npm ls docker-tester

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

Note: The npm ls docker-tester command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Docker tester, 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

OS Command injection vulnerability in Mintzo Docker-Tester through 1.2.1 allows attackers to execute arbitrary commands via shell metacharacters in the 'ports' entry of a crafted docker-compose.yml file.
