Loading vulnerability…
A remote code execution vulnerability exists in the QTS Media Library component of QNAP NAS devices, affecting all versions prior to QTS 4.2.6 build 20170905 and QTS 4.3.3.0299 build 20170901. The vulnerability is present in the transcoding service listening on port 9251, which allows unauthenticated remote attackers to execute arbitrary commands on the device.

This repository contains a single Metasploit module (modules/exploits/linux/misc/qnap_transcode_server.rb) that exploits an unauthenticated remote command injection vulnerability (CVE-2017-13067) in the QNAP Transcode Server, typically running on QNAP NAS devices. The exploit targets the service listening on TCP port 9251 and leverages the 'rmfile' command to inject arbitrary commands. The module uses Metasploit's CmdStager to deliver a payload (default: linux/armle/meterpreter_reverse_tcp) via wget or curl, resulting in a reverse shell on the target device. The exploit is weaponized, allowing for easy payload customization and reliable exploitation. The code is well-structured, with clear separation of check, command execution, and exploitation logic, and is suitable for operational use against vulnerable QNAP NAS devices.
