The vulnerability exists within /request_award.php.

$vbulletin->input->clean_array_gpc('p', array(
            'award_id' => TYPE_UINT,
            //'award_request_name' => TYPE_STR,
            //'award_request_recipient_name' => TYPE_STR,
            'award_request_reason' => TYPE_STR,
            'award_request_uid' => TYPE_UNIT,
    ));

> $award_request_uid = $vbulletin->GPC['award_request_uid'];
> > $db->query_write("INSERT INTO " . TABLE_PREFIX . "award_requests (award_req_uid, award_rec_uid, award_req_aid, award_req_reason) VALUES ('$award_request_uid', '$award_request_uid', '$award[award_id]', '". $db->escape_string($vbulletin->GPC['award_request_reason']) ."')");

$award_request_uid is used within an insert into statement, unsanitized.

Sursa: vBulletin Yet Another Awards System 4.0.2 SQL Injection ? Packet Storm

Nu e bun.

$vbulletin->input->clean_array_gpc('p', array(

'award_id' => TYPE_UINT,

//'award_request_name' => TYPE_STR,

//'award_request_recipient_name' => TYPE_STR,

'award_request_reason' => TYPE_STR,

'award_request_uid' => TYPE_UNIT,

));

Din tipurile de date vBulletin:

TYPE_UINT

Will check that it is an unsigned integer

Variabila e trecuta prin clean_array_gpc() ca unsigned integer. Ce zice ala acolo ca nu e sanitizat e gresit.
