How to Fix CVE-2021-23399

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

wincred fixed: Latest secure release 
npm install wincred@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 wincred

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-23399, inspect your project dependencies using npm:

npm ls wincred

Analyze the terminal output to locate any version of Wincred 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 wincred 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Wincred, 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

This affects all versions of package wincred. If attacker-controlled user input is given to the getCredential function, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.
