How to Fix CVE-2017-16076

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

proxy.js fixed: Latest secure release 
npm install proxy.js@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 proxy.js

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-16076, inspect your project dependencies using npm:

npm ls proxy.js

Analyze the terminal output to locate any version of Proxy.js 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 proxy.js 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-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature.

Source Advisory Statement

The `proxy.js` package is a piece of malware that steals environment variables and sends them to attacker controlled locations. All versions have been unpublished from the npm registry. ## Recommendation As this package is malware, if you find it installed in your environment, the real security concern is determining how it got there. If you have found this installed in your environment, you should: 1. Delete the package 2. Clear your npm cache 3. Ensure it is not present in any other package.json files on your system 4. Regenerate your registry credentials, tokens, and any other sensitive credentials that may have been present in your environment variables. Additionally, any service which may have been exposed via credentials in your environment variables, such as a database, should be reviewed for indicators of compromise as well.
