How to Fix GHSA-r4m5-47cq-6qg8

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

ftp-srv fixed: 2.19.6 
npm install ftp-srv@2.19.6
ftp-srv fixed: 3.1.2 
npm install ftp-srv@3.1.2
ftp-srv fixed: 4.3.4 
npm install ftp-srv@4.3.4
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 ftp-srv

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-r4m5-47cq-6qg8, inspect your project dependencies using npm:

npm ls ftp-srv

Analyze the terminal output to locate any version of Ftp srv in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.19.6), your application is affected.

Note: The npm ls ftp-srv 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Ftp srv, 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 `ftp-srv` from v1.0.0 onward to v4.3.3 are vulnerable to Server-Side Request Forgery (SSRF). The package fails to prevent remote clients to access other resources in the network, for example when connecting to the server through telnet. This allows attackers to access any network resources available to the server, including private resources in the hosting environment. ## Recommendation Upgrade to patched versions `^2.19.6, ^3.1.2, ^4.3.4` ## Workarounds Blacklisting the FTP Command PORT will prevent the server from exposing this behaviour through active connections until a fix is applied. ``` const ftp = new FtpSrv({ blacklist: ['PORT'] }); ```
