Humiliating IIS servers for fun and jail time

This article is a technical guide on identifying and exploiting vulnerabilities in Microsoft IIS (Internet Information Services) web servers during bug bounty assessments. The author details reconnaissance techniques using Shodan, Google dorking, and HTTP fingerprinting to locate IIS servers, followed by exploitation methods including internal IP disclosure, web.config access, path traversal, and authentication bypass techniques. The guide emphasizes that misconfigured IIS servers are common targets that often leak sensitive information and contain exploitable security flaws.
