My Journey to Uncovering Reflected XSS and HTML Injection in 4 Microsoft Subdomains
The Beginning
It was an ordinary morning, and I found myself pondering what to test next in the vast realm of bug bounty. My mind wandered through countless possibilities until it landed on an intriguing idea: testing Microsoft’s domains. With a spark of curiosity, I embarked on a journey to explore and uncover potential vulnerabilities.
The Exploration
Enumerating Subdomains
I began by enumerating subdomains, systematically probing each one for weaknesses. It was a meticulous process, but my excitement grew with every discovery. Among the myriad of subdomains, one particular domain caught my attention: appleconfigurator2.manage.microsoft.com.
The Discovery
Initial Test: Reflection in Path
My initial tests revealed something interesting. I entered some value into the path of the URL:
https://appleconfigurator2.manage.microsoft.com/BadRequest.html/value
To my surprise, the value was reflected in the response. This observation signaled a potential vulnerability, prompting me to delve deeper, and I got another new parametre //?aspxerrorpath.
Uncovering Reflected XSS
With a hypothesis forming in my mind, I decided to test for XSS. Reflected XSS occurs when a web application includes user input in its output without proper sanitization, allowing attackers to inject and execute malicious scripts. I crafted a payload and inserted it into the BadRequest parametre.
I started with payload: javascript:alert(1)
And I didn’t get any popup…
So I decided to run my #xss0r Tool on the path after “BadRequest.html” and with using — path option in my tool for supporting XSS in web paths.
This tool is designed to test for XSS vulnerabilities efficiently. As expected, it generated numerous alerts because I used over 3000 different encoding XSS payloads and confirming the presence of a Reflected XSS vulnerability. My tool made the process quick and seamless, demonstrating its effectiveness in identifying security issues.

Final URL for XSS:
Discovering HTML Injection
With the momentum from my XSS discovery, I shifted focus to test for HTML Injection. This vulnerability involves injecting arbitrary HTML content, leading to unauthorized actions and information disclosure.
Payload:
';a=prompt,a()//?aspxerrorpath=/MDMServiceConfig%20%3Cimg%20src=1%20onerror=alert(1)%3E%3Cdiv%20style=%22overflow:%20hidden;%20white-space:%20nowrap;%22%3E%3Cmarquee%20style=%22color:red;font-size:50px;%22%20behavior=%22scroll%22%20direction=%22left%22%20scrollamount=%2210%22%3EHACKED%20BY%20%3Cspan%20style=%22color:red;font-size:60px;%22%3E1BR0%3C/span%3E%3C/marquee%3E
FINAL URL:
https://appleconfigurator2.manage.microsoft.com/BadRequest.html';a=prompt,a()//?aspxerrorpath=/MDMServiceConfig%20%3Cimg%20src=1%20onerror=alert(1)%3E%3Cdiv%20style=%22overflow:%20hidden;%20white-space:%20nowrap;%22%3E%3Cmarquee%20style=%22color:red;font-size:50px;%22%20behavior=%22scroll%22%20direction=%22left%22%20scrollamount=%2210%22%3EHACKED%20BY%20%3Cspan%20style=%22color:red;font-size:60px;%22%3E1BR0%3C/span%3E%3C/marquee%3EExpanding the Search
With these findings, I decided to expand my search to other subdomains. I was eager to see if the vulnerabilities existed elsewhere. After thorough testing using my #xss0r Tool, I discovered the same Reflected XSS and HTML Injection vulnerabilities on three additional subdomains:
Domain 1: https://appleconfigurator2.manage-beta.microsoft.com
- HTML Injection PoC URL:
