CVE-2019-7256 is an unauthenticated operating-system command injection vulnerability in Linear eMerge E3-Series access control devices. The vulnerable card-scan decoding endpoint permits execution of attacker-controlled commands enclosed in grave accents (backticks). Attackers have exploited the vulnerability against Internet-exposed devices to deliver Ngioweb and ClingSTUN proxy malware.

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.
