How to Fix CVE-2020-10800

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

lix fixed: Latest secure release 
npm install lix@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 lix

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-10800, inspect your project dependencies using npm:

npm ls lix

Analyze the terminal output to locate any version of Lix 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 lix 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-544: Missing Standardized Error Handling Mechanism, where the product does not use a standardized method for handling errors throughout the code, which might introduce inconsistent error handling and resultant weaknesses. In Lix, 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

All versions of `lix` are vulnerable to Machine-In-The-Middle. The package accepts downloads with `http` and follows `location` header redirects for package downloads. This allows for an attacker in a privileged network position to intercept a lix package installation and redirect the download to a malicious source. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
