How to Fix CVE-2013-7370

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

connect fixed: 2.8.1 
npm install connect@2.8.1
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 connect

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2013-7370, inspect your project dependencies using npm:

npm ls connect

Analyze the terminal output to locate any version of Connect in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.8.1), your application is affected.

Note: The npm ls connect 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 Connect, 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

Connect is a stack of middleware that is executed in order in each request. The "methodOverride" middleware allows the http post to override the method of the request with the value of the "_method" post key or with the header "x-http-method-override". Because the user post input was not checked, req.method could contain any kind of value. Because the req.method did not match any common method VERB, connect answered with a 404 page containing the "Cannot `[method]` `[url]`" content. The method was not properly encoded for output in the browser. ###Example: ``` ~ curl "localhost:3000" -d "_method=<script src=http://nodesecurity.io/xss.js></script>" Cannot <SCRIPT SRC=HTTP://NODESECURITY.IO/XSS.JS></SCRIPT> / ``` ## Recommendation Update to the newest version of Connect or disable methodOverride. It is not possible to avoid the vulnerability if you have enabled this middleware in the top of your stack.
