Loading vulnerability…
A stack-based buffer overflow exists in the Core Server HMI Service (Coreservice.exe) of Scadatec Limited Procyon SCADA versions 1.06 and prior to 1.14. The vulnerability is triggered by sending an overly long password to the Telnet service (TCP/23), resulting in an out-of-bounds read or write. This can cause the service to crash and may allow remote code execution.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in the Procyon Core Server's coreservice.exe (versions 1.13 and earlier) on Windows. The exploit leverages improper bounds checking when processing a password, allowing an attacker to overwrite a structured exception handler (SEH) and execute arbitrary code remotely and unauthenticated. The module uses an egghunter to deliver a customizable Metasploit payload, avoiding specific bad characters. The default target is Windows XP SP3 with no DEP bypass, and the exploit connects to the service on TCP port 23 (commonly used for Telnet). The module includes a check method to verify the presence and version of the vulnerable service. Upon successful exploitation, the payload is executed with the privileges of the service, and the service is expected to recover after payload execution. The repository is structured as a single Ruby file compatible with the Metasploit framework.
