CVE-2013-7371 · Severity: low · CVSS 3.1 · Published 2022-05-05

Node Connect is a popular middleware library for the Node.js web platform that handles request processing. The methodOverride middleware contains a reflected cross-site scripting (XSS) vulnerability that allows attackers to inject arbitrary JavaScript code into error pages. When a user submits a crafted HTTP request, the unsanitized input is echoed back in the 404 error response, enabling account hijacking, session theft, or malware distribution to application users.

Vendors: [npm](https://junglewise.ai/threats/vendors/npm).

## How to fix

- connect (npm): upgrade to 2.8.2 or later

  ```


## Technical details

The vulnerability is a reflected XSS (CWE-79) in the methodOverride middleware, which allows HTTP POST requests to override the request method via the "_method" parameter or "x-http-method-override" header. The vulnerable code in proto.js line 155 constructs an error message ("Cannot [METHOD] [URL]") without properly escaping the req.method value, which comes directly from user input. An attacker can submit a POST request with _method=<script> content to trigger XSS in the 404 error page. The attack requires network access and user interaction (the victim must view the crafted response in a browser), but does not require authentication. The fix was implemented in version 2.8.2, which properly HTML-encodes the method value before rendering it in error responses.
