MyBB Profile Blogs plugin suffers from SQL Injection && Stored XSS.
|
|
The vulnerabilities exist withing profileblogs.php which located in /plugins/ folder.
|
|
|
|
|
|
#################################### SQLi ####################################
|
|
|
|
Instructions:
|
|
1. Create a new post in your profile blog.
|
|
2. Edit it.
|
|
3. Inject in edit GET parameter.
|
|
|
|
Vulnerable part:
|
|
<?php
|
|
|
|
/*Line 253*/ $pid = $mybb->input['edit'];
|
|
/*Line 259*/ $db->query("UPDATE `".TABLE_PREFIX."blogposts` SET `subject` = '".$subject."', `message` = '".$message."' WHERE `pid` = '".$pid."'");
|
|
|
|
?>
|
|
|
|
How to exploit it:
|
|
member.php?action=profile&uid=2&blogpage=1&edit=[VAILD_ID]'[SQLi]

#################################### Stored-XSS ####################################
|
|
|
|
The post subject is stored in the database without XSS protection, like this:
|
|
<?php
|
|
$subject = addslashes($mybb->input['subject']);
|
|
$db->query("INSERT INTO `".TABLE_PREFIX."blogposts` VALUES (NULL, '".$uid."', '".$dateline."', '".$subject."', '".$message."', '".$ipaddress."')");
|
|
?>
|
|
|
|
And also comes out without XSS protection:
|
|
|
|
<?php
|
|
/*328*/ while($post = $db->fetch_array($query)) {
|
|
/*333*/ $blog .= "<strong style=\"float: left;\">".$post['subject']."</strong><br />";
|
|
?>
|
|
|
|
As a result, we're getting Stored-XSS.
