CVE-2019-7256 is a remote code execution vulnerability in the Linear eMerge E3-Series building management system (version 1.00-06). The vulnerability exists in the 'card_scan.php' script, which fails to properly sanitize user-supplied input in the 'ReaderNo' parameter. This allows an attacker to inject arbitrary system commands via the web interface, which are executed with the privileges of the 'lighttpd' web server user. Exploitation can lead to privilege escalation to root, full device compromise, and potential lateral movement within critical infrastructure environments.

This repository contains a single Metasploit module targeting CVE-2019-7256, a command injection vulnerability in the Linear eMerge E3-Series Access Controller (versions 1.00-06 and below). The exploit leverages unauthenticated command injection in the 'card_scan_decoder.php' endpoint via the 'No' and 'door' HTTP GET parameters. The module supports two main payload types: direct command execution (e.g., reverse bash shell) and a Linux dropper for deploying a Meterpreter reverse shell (ARMLE architecture). The exploit executes commands as root, requiring the default root password ('davestyle') unless changed. The module includes a check method to verify vulnerability by timing a sleep command. The code is written in Ruby and is structured as a standard Metasploit exploit module, making it weaponized and easily customizable for attackers. The only fingerprintable endpoint is the '/card_scan_decoder.php' path, which is the target of the injection.
