phpKF-Portal is prone to multiple local file-include vulnerabilities because it fails to properly sanitize user-supplied input.
 
An attacker can exploit this vulnerability using directory-traversal strings to view local files within the context of the webserver process. Information harvested may aid in further attacks.
 
phpKF-Portal 1.10 is vulnerable; other versions may also be affected.
