2Wire DoS (Exploit)
------------------------------------------------------------------------
SUMMARY
Several models of <http://www.2wire.com/> 2Wire ADSL Modems/Gateways are
vulnerable to a denial of service attack. It's possible to cause a mode
reset by sending a maliciously crafted request.
DETAILS
Vulnerable Systems:
* 2Wire OfficePortal 0
* 2Wire HomePortal 1500W
* 2Wire HomePortal 100W
* 2Wire HomePortal 100S
* 2Wire HomePortal 1000W
* 2Wire HomePortal 1000SW
* 2Wire HomePortal 1000S
* 2Wire HomePortal 1000
* 2Wire HomePortal 0
Exploit:

//// [ Explanation ] this PoC make an evil_request
//// and send to the server , when the server process
//// it the request fall him, AND THE MODEM WILL RESET!.
////
//// [ Note ] This Poc was coded using Dev-C++ 4.9.9.2
//// If you have any error with the librarys you need
//// include libws2_32.a at the project.
