Unknown  
  
Vulnerabilities:  
1) Authentication bypass - the software sends a 301 Location redirect  
back to the login page, if an unauthenticated user requests an  
authenticated administration page. However on the PHP side the script  
does not exit(0); therefore you can use the system as an administrator  
and execute admin functions regardless, such as modifying documents by  
ignoring the redirect and interacting with the HTML content.  
  
2) There is a SQL injection in the user edit form e.g  
https://[target]/admin/users/edit.php?id=1  
  
(which is accessible as an "administrator" - exploit unauthenticated  
as per above).
