CVE-2016-6600 is a directory traversal vulnerability in the file upload functionality of ZOHO WebNMS Framework 5.2 and 5.2 SP1. The vulnerability exists in the FileUploadServlet, which fails to properly sanitize the fileName parameter, allowing remote unauthenticated attackers to upload arbitrary files (including JSP webshells) to locations outside the intended directory. This enables attackers to achieve remote code execution by uploading and executing malicious JSP files on the server.

This repository contains a single Metasploit module (webnms_file_upload.rb) that exploits an arbitrary file upload vulnerability (CVE-2016-6600) in WebNMS Framework Server 5.2 and 5.2 SP1. The exploit targets the FileUploadServlet endpoint, abusing a directory traversal flaw to upload a malicious JSP file to the server. Once uploaded, the JSP decodes and writes a platform-specific payload (Windows or Linux) to disk, executes it, and optionally cleans up. The exploit is weaponized, allowing the attacker to achieve remote code execution as the user running the WebNMS server. The module supports both Linux and Windows targets and is fully integrated into the Metasploit framework, providing payload selection and automated cleanup. The main network endpoints involved are the vulnerable file upload servlet and the location where the malicious JSP is accessed for execution.
