Description

This module exploits a buffer overflow on the Supermicro Onboard IPMI controller web
interface. The vulnerability exists on the close_window.cgi CGI application, and is due
to the insecure usage of strcpy. In order to get a session, the module will execute
system() from libc with an arbitrary CMD payload sent on the User-Agent header. This
module has been tested successfully on Supermicro Onboard IPMI (X9SCL/X9SCM) with firmware
SMT_X9_214.
