Reddit Top RSS - Cross-Site Scripting

What is the "Reddit Top RSS - Cross-Site Scripting" module?

The "Reddit Top RSS - Cross-Site Scripting" module is designed to detect a high severity cross-site scripting (XSS) vulnerability in the Reddit Top RSS software. Reddit Top RSS is a popular tool that allows users to retrieve and view the top posts from various subreddits using RSS feeds.

This module is specifically focused on identifying potential XSS vulnerabilities within the Reddit Top RSS software, which could allow attackers to inject malicious scripts into the application and potentially compromise user data or perform unauthorized actions.

The module was created by an unknown author and is part of the Vidoc platform's scanning capabilities.


A successful exploitation of the XSS vulnerability in the Reddit Top RSS software could have serious consequences, including:

- Potential theft of sensitive user information - Unauthorized access to user accounts - Manipulation of displayed content - Possible spread of malware or malicious scripts

It is crucial to address this vulnerability promptly to mitigate these risks and protect user data.

How does the module work?

The "Reddit Top RSS - Cross-Site Scripting" module works by sending HTTP requests to the Reddit Top RSS software and analyzing the responses for specific patterns that indicate the presence of an XSS vulnerability.

One example of an HTTP request sent by the module is:

GET /?subreddit=news&score=2134%22%3E%3Cscript%3Ealert%28document.domain%29%3C%2Fscript%3E HTTP/1.1

The module then applies a set of matching conditions to the response, including:

- Checking if the response body contains the pattern value="2134"><script>alert(document.domain)</script>" min="0" - Verifying that the response header indicates a content type of text/html - Ensuring that the response status code is 200

If all of these conditions are met, the module identifies the presence of an XSS vulnerability in the Reddit Top RSS software.

It is important to address any identified vulnerabilities promptly to prevent potential exploitation and protect user data.
