OSCP-buffer-overflow-prep

So recently, I started off with some basic exploit development, Here is a collection of all the stack overflow exploits I programmed for practicing Buffer OverFlows! I soon will be uploading all the exploits in this repository!

Steps

  • Finding a vulnerable entry point in the program
  • Finding the offset
  • Controlling EIP
  • Finding Bad Characters
  • Finding JMP ESP Instruction [Note: If ASLR or any other kind of protection is used in the binary, you might have to bypass them, I haven't learnt that yet]
  • Generating shellcode and boom!

List of programs I exploited till now!

  • VulnServer
  • FreeFloat FTP Server 1.0
  • Server-STRCPY
  • Brainpan
  • Brainstorm
  • OSCP Buffer Overflow Practice (TryHackMe) (Haven't done all 10, 6 more to go!)

Download Binaries

  • If you want to practice buffer overflows, I have also uploaded the executable files above which you can simply download and practice!
