Procyon Core Server HMI Coreservice.exe Stack Buffer Overflow

Description

This module exploits a vulnerability in the coreservice.exe component of Proycon
Core Server fails to do proper bounds checking before copying data into a small buffer on the stack.
This causes a buffer overflow and allows to overwrite a structured exception handling
record on the stack, allowing for unauthenticated remote code execution. Also, after the
payload exits, Coreservice.exe should automatically recover.
