CVE-2020-12027 is part of a critical vulnerability chain in Rockwell FactoryTalk View SE (version 11.00.00.230) that enables unauthenticated remote code execution as the IIS user on Windows. The chain leverages an unauthenticated project copy request, directory traversal, a race condition, and two information leak vulnerabilities in REST endpoints exposed by hmi_isapi.dll on Microsoft IIS. The information leak component (CVE-2020-12027) allows unauthenticated attackers to enumerate project names and file paths, facilitating reliable exploitation of the subsequent vulnerabilities in the chain. The attack can be performed in the default configuration and does not require authentication.

This repository contains a single Metasploit module (rockwell_factorytalk_rce.rb) targeting Rockwell Automation FactoryTalk View SE SCADA software. The exploit chains five vulnerabilities (including unauthenticated project copy, directory traversal, race condition, and two information leaks) to achieve unauthenticated remote code execution as the IIS user. The module is operational and provides a reverse shell (Meterpreter) or other payload via PowerShell/ASP, exploiting the web interface (typically at /rsviewse/) and the vulnerable /hmi_isapi.dll endpoint. The exploit was used in Pwn2Own Miami 2020 and is confirmed to work against version 11.00.00.230. The code is written in Ruby and is structured as a standard Metasploit exploit module, with options for configuring the attacker's HTTP server and the target's base path. The attack vector is network-based, requiring the attacker to serve payloads to the target over HTTP. The module is not a detection script and is not fake; it is a real, operational exploit.
