Procyon Core Server HMI Coreservice.exe Stack Buffer Overflow

Description

This module exploits a vulnerability in the coreservice.exe component of Proycon Core Server <= v1.13. While processing a password, the application 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.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
