EasySite 2.0 - 'skin_chooser.php' Remote File Inclusion

source: https://www.securityfocus.com/bid/28563/info
  
EasySite is prone to multiple remote file-include vulnerabilities because it fails to sufficiently sanitize user-supplied data.
  
Exploiting these issues may allow an attacker to compromise the application and the underlying system; other attacks are also possible.
  
EasySite 2.0 is vulnerable; other versions may also be affected.
