ocPortal CMS 7.1.5 Open Redirect

`1. OVERVIEW  
  
ocPoral CMS 7.1.5 and lower versions are vulnerable to Open URL Redirection.  
  
  
2. BACKGROUND  
  
ocPortal is the website Content Management System (a CMS) for building  
and maintaining a dynamic website. ocPortal's powerful feature-set  
means there's always a way to accomplish your vision. Not only does  
ocPortal's CMS have all the features you'd expect: for instance photo  
galleries, news, file downloads and community forums/chats, but it  
does so whilst meeting the highest accessibility and professional  
standards. It is also smart enough to go beyond page management, to  
automatically handle search engine optimisation, and provide  
aggressive hack attack prevention.  
  
  
3. VULNERABILITY DESCRIPTION  
  
ocPoral CMS 7.1.5 and lower versions contain a flaw that allows a  
remote cross site redirection attack. This flaw exists because the  
application does not properly sanitise the "redirect" parameter. This  
allows an attacker to create a specially crafted URL, that if clicked,  
would redirect a victim from the intended legitimate web site to an  
arbitrary web site of the attacker's choice.
