CVE-2013-3623 is a stack-based buffer overflow vulnerability in the close_window.cgi component of the web interface in Supermicro Intelligent Platform Management Interface (IPMI) firmware prior to version 3.15 (SMT_X9_315) on X9 generation motherboards. The vulnerability exists due to insufficient bounds checking on the 'sess_sid' and 'ACT' parameters, allowing remote attackers to overflow the stack and execute arbitrary code as root via crafted HTTP requests.

This repository contains a single Metasploit module (modules/exploits/linux/http/smt_ipmi_close_window_bof.rb) that exploits a buffer overflow vulnerability (CVE-2013-3623) in the Supermicro Onboard IPMI controller's web interface, specifically in the close_window.cgi CGI application. The exploit leverages insecure usage of strcpy in the CGI script, allowing an attacker to overflow a buffer by sending a specially crafted HTTP POST request to /cgi/close_window.cgi. The payload, which is an arbitrary system command, is delivered via the User-Agent HTTP header and executed on the target system using system() from libc. The module is operational and provides remote code execution capabilities on affected devices. The code is written in Ruby and is designed to be used within the Metasploit framework. The only fingerprintable endpoint is the /cgi/close_window.cgi path on the target device.
