CVE-2023-47218 is an unauthenticated OS command injection vulnerability in the quick.cgi component used by several QNAP operating system versions, including QTS, QuTS hero, and QuTScloud. QNAP states that, if exploited, the issue could allow users to execute commands via a network. Supporting reporting indicates the flaw is exploitable by sending a specially crafted HTTP POST request to quick.cgi. Rapid7 reported the issue and published a proof-of-concept exploit. The vulnerable quick.cgi component is noted to be present on uninitialized QNAP NAS devices and disabled after successful device initialization, which may limit exposure in some deployments.

This repository contains a single Metasploit module (modules/exploits/linux/http/qnap_qts_rce_cve_2023_47218.rb) targeting CVE-2023-47218, an unauthenticated remote code execution vulnerability in QNAP QTS and QuTS hero NAS devices. The exploit leverages a command injection flaw in the /cgi-bin/quick/quick.cgi endpoint, which is exposed on uninitialized QNAP NAS devices. The module checks for vulnerability by sending a GET request to the endpoint and analyzing the response. If vulnerable, it uploads a bash script containing the encoded payload to a writable directory (/mnt/update) and executes it via command injection. The exploit is operational, allowing arbitrary command execution as a privileged user. The only endpoints referenced are the vulnerable CGI path and the writable directory used for payload delivery. The code is written in Ruby and is structured as a standard Metasploit exploit module.
