MyBB editpost.php SQL Injection

`MyBB <1.6.9 is vulnerable to Stored, Error based, SQL Injection.  
  
Vulnerable code:  
  
/editpost.php  
  
===  
Line 398  
===  
$posthash_query = "posthash='{$posthash}' OR ";  
===  
  
  
It can be done by using Tamper Data(Or Live HTTP Headers), and when  
submitting a post, edit the 'posthash' POST parameter to your payload,  
submitting, then going to edit your post.
