CVE-2023-40289 is a command injection vulnerability affecting Supermicro X11SSM-F, X11SAE-F, and X11SSE-F devices running BMC firmware version 1.66. The flaw exists in the BMC web interface and allows improper neutralization of attacker-controlled input before it is used in an operating system command. A user who already has BMC administrative privileges can exploit the issue to inject and execute arbitrary commands on the management controller, resulting in privilege escalation within the BMC environment.

This repository provides a fully functional exploit for CVE-2023-40289, a command injection vulnerability in ATEN's BMC firmware, commonly found in Supermicro and Aspeed server platforms. The main exploit script (CVE_2023_40289.py) is a Python 3 tool that allows an authenticated attacker (with admin credentials or session) to execute arbitrary shell commands on the BMC via the web interface. The script supports three main operations: 'get' (download files from the BMC), 'put' (upload files to the BMC), and 'run' (execute arbitrary commands). It achieves this by injecting shell commands into the 'mail' parameter of a POST request to the BMC's web UI, exploiting the vulnerable configuration alert functionality. The exploit also sets up a local HTTP server to receive exfiltrated files or command output from the BMC. The repository includes a README with detailed usage instructions and examples, a pyproject.toml for dependencies, and an MIT license. The exploit is operational and provides full compromise of the target BMC, including file manipulation and command execution.
