Cisco Data Center Network Manager (DCNM) contains an incorrect permission-setting vulnerability in its web-based management interface. An unauthenticated remote attacker can connect to the interface and request specific URLs to download arbitrary files from the underlying filesystem, including sensitive files.

This repository contains a single Metasploit auxiliary module (modules/auxiliary/admin/networking/cisco_dcnm_download.rb) targeting Cisco Data Center Network Manager (DCNM) versions 10.4(2), 11.0(1), and 11.1(1). The module exploits an unauthenticated (or, for 11.0(1), authenticated) arbitrary file download vulnerability via the /fm/downloadServlet endpoint. The attacker can specify any file path (default: /etc/shadow) to download files as root from the DCNM server. The module includes logic to detect the DCNM version and handle authentication as needed. The exploit is operational and can be used to exfiltrate sensitive files from vulnerable DCNM instances. The code is written in Ruby and is designed to be run within the Metasploit framework.
