CVE-2019-1937 is an authentication bypass vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data. The vulnerability arises from insufficient validation of request headers during the authentication process, allowing an unauthenticated remote attacker to acquire a valid session token with administrator privileges. By sending a crafted series of HTTP requests with specific headers, an attacker can bypass authentication and gain full administrative access to the affected device. This flaw is present in Cisco UCS Director versions 6.6.0 and 6.7.0, among others.

This repository contains a single Metasploit module (modules/exploits/linux/http/cisco_ucs_rce.rb) targeting Cisco UCS Director virtual appliances. The exploit leverages two vulnerabilities: CVE-2019-1937 (authentication bypass) and CVE-2019-1936 (command injection). The module first bypasses authentication to obtain an admin session, then exploits a command injection flaw in a password change form to execute arbitrary commands as root. The default payload is a bash reverse shell, but any Metasploit-compatible command payload can be used. The exploit is unauthenticated and works over HTTPS, targeting the /app/ui/login and /app/ui/ClientServlet endpoints. The code is operational and provides root shell access if successful. The repository is structured as a single Ruby file compatible with the Metasploit framework.
