## Description:   
----------------------------------------------------------------  
Simple IP Ban is a lightweight ip / user agent ban plugin.  
  
## CSRF:  
----------------------------------------------------------------  
It is possible to change the plugins admin settings by tricking a logged in admin to visit a crafted page.   
  
## Stored XSS:  
----------------------------------------------------------------  
Settings data from the admin page is stored unsanitized and shown on the plugin's admin page. This allows an attacker to perform XSS through the settings fields.
