Module Overview

Name: Supermicro Onboard IPMI Static SSL Certificate Scanner
Module: auxiliary/scanner/http/smt_ipmi_static_cert_scanner
Source code: modules/auxiliary/scanner/http/smt_ipmi_static_cert_scanner.rb
Disclosure date: 2013-11-06
Last modification time: 2020-02-18 08:58:30 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 443
List of CVEs: CVE-2013-3619

This module checks for a static SSL certificate shipped with Supermicro Onboard IPMI controllers. An attacker with access to the publicly-available firmware can perform man-in-the-middle attacks and offline decryption of communication to the controller. This module has been on a Supermicro Onboard IPMI (X9SCL/X9SCM) with firmware version SMT_X9_214.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/http/smt_ipmi_static_cert_scanner
msf auxiliary(smt_ipmi_static_cert_scanner) > show options
    ... show and set options ...
msf auxiliary(smt_ipmi_static_cert_scanner) > set RHOSTS ip-range
msf auxiliary(smt_ipmi_static_cert_scanner) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(smt_ipmi_static_cert_scanner) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(smt_ipmi_static_cert_scanner) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(smt_ipmi_static_cert_scanner) > set RHOSTS file:/tmp/ip_list.txt

Required Options

  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
