How to Fix CVE-2021-4326

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

@zowe/imperative fixed: 5.7.1 
npm install @zowe/imperative@5.7.1
@zowe/imperative fixed: 4.18.10 
npm install @zowe/imperative@4.18.10
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 @zowe/imperative

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-4326, inspect your project dependencies using npm:

npm ls @zowe/imperative

Analyze the terminal output to locate any version of @zowe/imperative in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.7.1), your application is affected.

Note: The npm ls @zowe/imperative 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-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In @zowe/imperative, 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

A vulnerability in Imperative framework which allows already-privileged local actors to execute arbitrary shell commands via plugin install/update commands, or maliciously formed environment variables. Impacts Zowe CLI.
