[ What is Hasbani-WindWeb/2.0 ]

Hasbani server is a httpd created for menaging ethernet routers and adsl modems.

[ Why HTTPD crash? ]

Causes of DoS are not perfecly known by me 'cos i can't debug a chip-integrated http daemon.
Btw seems that Hasbani enter a loop in a GET /..:..:..etc. condition, causes that when an attacker reguest a long crafted string
server enter an endless loop with conseguenly crash of the httpd.

NOTE: This exploit DON'T drop down victim's adsl connection!
