Web Hacking Expert - Full-Stack Exploitation Mastery - HTTP Parameter Pollution – Part 1

The video tutorial explains HTTP parameter pollution, a security vulnerability that can bypass authorization by sending multiple occurrences of the same parameter in a request. The instructor provides a demo of a money transfer scenario to illustrate the attack, highlighting how ambiguity in parameter handling can lead to exploitation. The tutorial also covers the technical aspects of data transmission between web applications and services.

How does the web application determine which parameter to process when multiple occurrences are present?

Discuss the role of ambiguity in the exploitation scenarios mentioned in the text.
