How it was found

Summary:

Hello, When hunting for your web application.

I have managed to go https://cars.fas.gsa.gov/cars/cars and get displayed with a form. I have already tried to login to Cars and without success. However i've noticed the loginChk() function and change the value of the form hence bypassing it and logging in succesfuly.

Steps To Reproduce:

  1. go to https://cars.fas.gsa.gov/cars/cars
  2. type loginChk() function in console.
  3. It would return false.
  4. Now type in console ( can be opened using F12). document.forms[0].scSelCen.value = "admin"
  5. Now try to login by clicking on CARS button.

Supporting Material/References:

Navigator used : google chrome.

If you need any additional information. feel free to ask me.

PS : I think the website went for a maintenance right now. Even though i didn't use anything of that panel.

Impact

Any attacker would have the access to admin panel and do whatever he wants. As i can see , it's a platform for reporting accidents.
