CVE-2023-40504 is a command-injection vulnerability in LG Simple Editor's readVideoInfo method. Insufficient validation of a user-controlled string before it is used in a system call permits remote, unauthenticated attackers to execute arbitrary code with SYSTEM privileges.

This repository contains a single Metasploit module targeting an unauthenticated command injection vulnerability (CVE-2023-40504) in LG Simple Editor versions up to 3.21.0 on Windows. The exploit leverages a vulnerability in the /simpleeditor/imageManager/uploadVideo.do HTTP endpoint, where a crafted multipart/form-data POST request allows arbitrary OS command execution as NT AUTHORITY\SYSTEM. The module includes a version check using the /simpleeditor/common/commonReleaseNotes.do endpoint to determine if the target is vulnerable. The exploit is fully weaponized, allowing the attacker to specify arbitrary commands or Metasploit payloads, and is suitable for remote, unauthenticated exploitation over the network. The code is written in Ruby and follows standard Metasploit module structure, with clear separation of version checking, exploitation, and payload delivery logic.
