How to Fix CVE-2018-16484

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

m-server fixed: 1.4.2 
npm install m-server@1.4.2
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 m-server

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-16484, inspect your project dependencies using npm:

npm ls m-server

Analyze the terminal output to locate any version of M server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.2), your application is affected.

Note: The npm ls m-server 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In M server, 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

Versions of `m-server` before 1.4.2 are vulnerable to stored cross-site scripting. This vulnerability is exploitable if an attacker is able to control the name of a file that `m-server` is serving. ## Recommendation Update to version 1.4.2 or later.
