Python Web Penetration Testing Cookbook

Header-based Cross-site scripting

Until now, we have focused on sending payloads through URLs and parameters, the two obvious methods of performing attacks. However, there are numerous rich and fertile sources of vulnerabilities that often lay untouched. One of these will be covered in depth in Chapter 6, Image Analysis and Manipulation, for which we can give an intro now. Logs are often kept of specific headers of users that are accessing web pages. It can be a worthwhile activity performing checks against these logs by performing XSS attacks in headers.

We will be creating a script that submits XSS attack strings to all available headers and cycles through several possible XSS attacks. We will provide a short list of payloads, grab all the headers, ...
