How to Fix CVE-2016-10532

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

console-io fixed: 2.3.0 
npm install console-io@2.3.0
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 console-io

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2016-10532, inspect your project dependencies using npm:

npm ls console-io

Analyze the terminal output to locate any version of Console io in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.0), your application is affected.

Note: The npm ls console-io 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Console io, 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

Affected versions of the `console-io` package do not configure the underlying websocket library to require authentication, resulting in an authentication bypass vulnerability. As `console-io` allows terminal access on the server via a web page, an authentication bypass is essentially remote code execution. ## Recommendation Update to version 2.3.0 or later.
