How to Fix CVE-2017-16155

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

fast-http-cli fixed: Latest secure release 
npm install fast-http-cli@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 fast-http-cli

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-16155, inspect your project dependencies using npm:

npm ls fast-http-cli

Analyze the terminal output to locate any version of Fast http cli 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 fast-http-cli 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Fast http cli, 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

`fast-http-cli` is the command line interface for `fast-http`, a simple web server. `fast-http-cli` is vulnerable to a directory traversal issue, giving an attacker access to the filesystem by placing "../" in the url. **Example request:** ```http GET /../../../../../../../../../../etc/passwd HTTP/1.1 host: localhost ``` and server Response: ```http HTTP/1.1 200 OK Date: Thu, 04 May 2017 23:59:18 GMT Connection: keep-alive Transfer-Encoding: chunked {contents of /etc/passwd} ``` ## Recommendation No patch is available for this vulnerability. It is recommended that the package is only used for local development, and if the functionality is needed for production, a different package is used instead.
