Buffer Overflow - Hacking websites

I asked a friend how he could get into websites and change information on them.
he told me he had 2 ways, buffer overload, which was the easy way,
and FTP which was the hard way. Does anyone know how to Buffer overload
a website? Are there any programs or software needed? please share any
information. Thanks

 

well you can also sql inject a site which will be A LOT easier than those ways trying using google search.

type

Buffer overload script or something of that nature

 

which one is more easier. SQL injection or this buffer overload.

 

well i would think SQL injection, but i don't know if SQL injection allows you to change the website.
i've done reserach on SQL injection, but i don't really understand how to, can someone tell me how its done? any programs to download?
