CVE-2016-20017 is a remote unauthenticated command injection vulnerability affecting D-Link DSL-2750B devices before firmware version 1.05. The flaw is exposed through the web management interface in login.cgi, where the cli parameter can be manipulated to inject and execute arbitrary operating system commands. Because the vulnerable endpoint is reachable without authentication, a remote attacker can send a crafted HTTP request directly to the device and cause command execution in the context of the underlying system. The vulnerability has been publicly reported as exploited in the wild over multiple years and has been incorporated into botnet propagation chains targeting internet-exposed embedded devices.

This repository contains a single Metasploit module (Ruby file) that exploits a remote command injection vulnerability (CVE-2016-20017) in D-Link DSL-2750B routers running firmware versions 1.01 to 1.03. The exploit leverages the 'cli' parameter in the /login.cgi HTTP endpoint, which is unsafely passed to the 'ayecli' binary, allowing unauthenticated attackers to execute arbitrary commands on the device. The module first checks if the target is a vulnerable DSL-2750B by requesting /ayefeaturesconvert.js and parsing the firmware version. If the target is vulnerable, it uses Metasploit's command stager to deliver and execute a payload (such as a reverse shell) on the device. The exploit is operational and provides full remote code execution capabilities. The code is structured as a standard Metasploit module, with clear separation of check, exploit, and payload delivery logic.
