Details:  
=========  
  
CSRF vulnerability in D-link DIR 615 wireless router enables an attacker to perform unwanted actions on router, which may lead to gaining full control of the device.   
  
  
  
Proof Of Concept:  
================  
  
1) User login to D-link DIR 615 wireless router  
  
2) User visits the attacker's malicious web page (DlinkCSRF.html)  
  
3) DlinkCSRF.html exploits CSRF vulnerability and changes the Security Options to None  
  
  
  
This is the CSRF POC for changing the Security option from WPA2 to None( Parameter: Method)  
  
Attacker can also tamper following parameters  
  
hiddenSSID  
SSID  
Passwords for all the applicable security options
