How to Fix CVE-2021-23451

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

otp-generator fixed: 3.0.0 
npm install otp-generator@3.0.0
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 otp-generator

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-23451, inspect your project dependencies using npm:

npm ls otp-generator

Analyze the terminal output to locate any version of Otp generator in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0), your application is affected.

Note: The npm ls otp-generator 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-330: Use of Insufficiently Random Values, where the product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. In Otp generator, 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

The package otp-generator before 3.0.0 are vulnerable to Insecure Randomness due to insecure generation of random one-time passwords, which may allow a brute-force attack.
