'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.
