    [align=center] Password Form Buffer Overflows[/align]
    [list]
    [*]In this Lesson we will be learning how to do a Login/Password Form Buffer Overflow. This is a very basic version of a Buffer Overflow but just as effective. Basically what is happening here is that Password Forms usually have a limit on the number of Characters they are aloud input, but we will bypass this limit overloading the login and getting access to the Server![/*:m][/list:u]
    [list]
    [*]To do this we will need a tool call WebDeveloper for Firefox, which you can download here[/*:m][/list:u]
    [list]
    [*]This is a very simple Hack so it only works on some Basic Authentication Logins, but its good know for the future if you find any! So on firefox Go Tools>Web Developer>Forms>Remove Maximum Lengths Now type in a massively long code eg "aaaaaaaaaaaaaaaaaaaaaaaaa" and so on, and it should come up with an error page either showing the encrypted passwords, or clear text passwords on the server! [/*:m][/list:u]
    [align=center]Congratulations now you know a simple Form Buffer Overflow!

    Pretty obvious it will.

    Anyway for people more interested in buffer overflows I would recommend the book "hacking the art of exploitation" it will describe you the complete process that comes along with buffer overflows in assembly language.

    I don't know whether to consider this a BoF or not lol. If so, Its a very simple type because BoF's can be quite complex and sometimes need Assembler knowledge. Good tutorial though.[hr]

    I have a pdf, i just find it easier with hard copys, and yeah im learning assembler, and buffer overflows atm, i have already coded one from scratch on some old software , its a good feeling when you get a shell appear
