Description

You are presented with a SecureVault authentication terminal compiled for RISC-V 64-bit. The program contains a stack buffer overflow. Your goal is to exploit it using Return-Oriented Programming (ROP) to gain access. Techniques required: - Finding the offset to the return address - Locating gadgets - Building a basic ROP chain This challenge is designed as an introduction to ROP on the RISC-V architecture. Note: The binary is statically linked and has no stack canary or PIE.
