How I exposed the teacher’s Aadhaar card, bank details on the college website.
Hey fellow hackers and Bug hunters,
After the long gap between me and Bug hunting, I am back with a write-up.
Once a day I finished my intern work and I went for playing cricket with my friends. They asked me if you were having GOOGLE honorable mentions but it doesn’t mean you are a real hunter. He said like if you are a real hunter can you able to retrieve my information on my college website.
As usual, I am not going to disclose the target webpage. I visited his college webpage and explore the functionalities. As soon as I saw the staff login page. I moved to the login page. As usual, if we see a login page, we will surely give it a try for SQLi. I tried some payloads but I can’t able to type the payload in the textbox, There’s a client-side validation for stopping these types of injections.
But, There's only a client-side validation only.
Opened my burp captured the request edited the username parameter to “admin’ or ‘1’=’1'#” and sent the request…BOOOOM!!!!. I logged in as ADMIN with admin privileges.
POST /Staff/loginProcess.jsp?submit=Log%20In HTTP/1.1

After I logged in as admin, I can able to retrieve all the information about the students. Even I can see any of the teacher’s full details. I was like WTF!!!
