Mikrotik Chimay Red Stack Clash Exploit is a vulnerability in Mikrotik RouterOS that allows an attacker to execute arbitrary code on the target system. The exploit is based on BigNerd95's POC and was tested on RouterOS 6.38.4 (x86). The exploit uses a technique called 'stack clash' which involves overflowing the stack of a thread and then using a ROP chain to execute arbitrary code. The exploit is written in Python and uses the pwntools library to generate the payload.
