CVE-2019-1936 is an authenticated command injection 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 user-supplied input in the SCP user password change functionality, specifically in the SCPUserConfigurationForm Java class. An attacker with administrator privileges can exploit this flaw by sending a crafted request to the web interface, resulting in arbitrary command execution on the underlying Linux shell as the root user.

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.
