COMPLETE Summary
Multiple stack-based buffer overflows in cgi/close_window.cgi in the web interface in the Intelligent Platform Management Interface (IPMI) with firmware before 3.15 (SMT_X9_315) on Supermicro X9 generation motherboards allow remote attackers to execute arbitrary code via the (1) sess_sid or (2) ACT parameter.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

Metasploit
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. id MSF:EXPLOIT/LINUX/HTTP/SMT_IPMI_CLOSE_WINDOW_BOF last seen 2020-06-02 modified 2020-02-18 published 2013-11-07 references reporter Rapid7 source https://github.com/rapid7/metasploit-framework/blob/master//modules/exploits/linux/http/smt_ipmi_close_window_bof.rb title Supermicro Onboard IPMI close_window.cgi Buffer Overflow description This module checks for known vulnerabilities in the CGI applications of Supermicro Onboard IPMI controllers.
