Explanation:

I've done a quick research on this platform.. just pen-tested it, not tested..
I have found some problems that affect this script:

1 - Admin bypass:

admin/index.php, line 13:

if( !es_islogged() ){
        header( "Location: login.php" );
}

really need an explanation? 0_o

2 - captcha bypass

admin/config.php, line 40:

if( $_POST['es_security_captcha'] == $_SESSION["es_security_captcha"] )

simply do not call the file captcha.php, and do not set a post variable named 'es_security_captcha' to bypass

3 - spamming/anon mailing (not tested)

while into the ACP you can set a new mail for the admin.. putting the mail you want and attacking the site
with special forged HTTP_USER_AGENT headers you can send a mail with (also) the text you want
