ASUS’S ADMIN PANEL AUTH BYPASS

So this is the write up for my Asus’s admin panel bypass report that most of my friends were asking me. If you have private programs to test feel free to contact me on https://twitter.com/by6153

The vulnerability was within their (.in) domain (asus.in) it was a PHP based admin panel and the vulnerability were:

1: forced browsing. (Want to know more? click here)

2: HTTP response tampering. (want to know more? Click here)

To exploit this I had three ways.

1: NoRedirect (Firefox Add-on)

2: Turning off JavaScript of browser.

3: HTTP response tampering via Burp suite.

========================================

Asus’s Admin panel Login page

========================================

URL: http://asus.in/where-to-buy/webadmin/index.php

As you can see index.php is the login page. So here I brute forced the current directory with Dirbuster and got dashboard.php is present there but directly we can’t access it so here I turned off JavaScript and browsed it again and got access to the panel and tried with no redirect add-on and it was working too. Then I tried HTTP response tampering via Burp Suite and got success. Below is video POC.

Dec 4, 2018 at 8:38 PM — I had Resend the report to them and they answered this time on.

Dec 5, 2018 at 8:21 AM and fixed it.

I must say they are too slow to answer to your reports.
