ELF32 ROP

Overflow a 32-bit binary and redirect execution into the win function.

Overflow a 32-bit binary and redirect execution into the win function with the correct arguments. Remember, arguments are typically passed differently on x86...

Overflow a 32-bit binary and redirect execution into system. Setuid has already been called for you!

Overflow a 32-bit binary and redirect execution into 2 win functions.

This can technically be cheesed because the flag is constant across runs, but doing that won't teach you anything! Calling consecutive functions during a single execution is crucial for the upcoming challenges.

Overflow a 32-bit binary and redirect execution into 2 win functions with the correct arguments. Remember, arguments have to be manually cleaned up on x86!

This can technically be cheesed because the flag is constant across runs, but doing that won't teach you anything! Calling consecutive functions during a single execution is crucial for the upcoming challenges.

Overflow a 32-bit binary to call setuid and system to obtain a shell.

Overflow a 32-bit binary to call setuid and system to obtain a shell. Use the PLT to bypass ASLR.

Overflow a 32-bit PIE binary to call setuid and system to obtain a shell. A PIE leak is provided, but no libc leak is given.

Hint: A saved register value on the stack is corrupted when a buffer overflow takes place. This value must be restored correctly when calling the PLT when PIE is enabled. Research System V i386 ABI standard conventions.
