'Name' => 'SonicWall SSL-VPN NetExtender ActiveX Control Buffer Overflow',
'Description' => %q{
This module exploits a stack buffer overflow in SonicWall SSL-VPN NetExtender.
By sending an overly long string to the "AddRouteEntry()" method located
in the NELaunchX.dll (1.0.0.26) Control, an attacker may be able to execute
arbitrary code.
