# Windows Exploit Suggester
# 
# DESCRIPTION
# 
# This tool compares a targets patch levels against the Microsoft vulnerability
# database in order to detect potential missing patches on the target. It also
# notifies the user if there are public exploits and Metasploit modules
# available for the missing bulletins.
#
# It requires the 'systeminfo' command output from a Windows host in order to
# compare that the Microsoft security bulletin database and determine the 
# patch level of the host.
#
# It has the ability to automatically download the security bulletin database
# from Microsoft with the --update flag, and saves it as an Excel spreadsheet.
#
# When looking at the command output, it is important to note that it assumes
# all vulnerabilities and then selectively removes them based upon the hotfix
# data. This can result in many false-positives, and it is key to know what
# software is actually running on the target host. For example, if there are
# known IIS exploits it will flag them even if IIS is not running on the
# target host.
#
# The output shows either public exploits (E), or Metasploit modules (M) as
# indicated by the character value.

# LIMITATIONS
#
# Currently, if the 'systeminfo' command reveals 'File 1' as the output for
# the hotfixes, it will not be able to determine which are installed on
# the target. If this occurs, the list of hotfixes will need to be 
# retrieved from the target host and passed in using the --hotfixes flag
#
# It currently does not seperate 'editions' of the Windows OS such as
# 'Tablet' or 'Media Center' for example, or different architectures, such as
# Itanium-based only
#
# False positives also occur where it assumes EVERYTHING is installed
# on the target Windows operating system. If you receive the 'File 1'
# output, try executing 'wmic qfe list full' and feed that as input
# with the --hotfixes flag, along with the 'systeminfo'

# TODOLIST
#
# TODO better if/then/case when detecting OS. more flexibility with parsing
#     different systeminfo output
# TODO seperate by editions? may result in false positives
# TODO count the number of exploits in the summary prior to outputting it?
# TODO finish -s --search function so that all info on an MS number can be
#      returned
# TODO add titles to exploit list so that it is more portable
# TODO test for Windows RT systeminfo output
# TODO improved msf/poc output? perhaps adding details on each MS number?
# TODO if it's running on windows, then try and execute the systeminfo command?
# TODO SPEED. this is now way too slow...  somewhat improved!
# TODO automatically install python module? xlrd.
# TODO manually override MS11-011 for Non-Affected Products. The bulletin
# database is wrong.

#
# CHANGE LOG
# v33 2017-02-13
# - added links to exploits and resources for each bulletins. can be ignored with the -q/--quiet flag
# - hard coded ms11-011 to ignore false positives
# - added additional resources
#
# v31 2016-02-10
# - changed bulletin url, microsoft 404'd it
#	
# v30 2016-01-04
# - added exploits and bulletins from the past six months
#
# v29 2015-09-16
# - adding support for windows 10
#
# v28 2015-07-30
# - added bulletin scraping for xlsx and xls files using regex. thanks to
#   edebernis for reporting the bug
# - added ms15-022, ms15-015 update to msf
#
# v27 2015-06-18
# - added new bulletin url that is only xls and not xlsx. thanks to bstork for
#   reporting the bug
# - added ms15-010, ms15-051, and ms15-052
#
# v26 2015-06-02
# - small bug fix with linked output
# - added duplicates flag that can allow for bulletins to be displayed
#   multiple times. this will allow for greater analysis on linked bulletins
#
# v25 2015-05-18
# - added ms15-051 local priv
#
# v24 2015-01-30
# - added --sub/-s command in order to display output of msids as linked
#   this aides in demonstrating what patches need to be applied precisely. 
#   this change was implemented in v23, but only followed the depth to level
#   1 instead of the entire way.
# - fixed a bug that know allows for multiple supercedes msids in the db
# - allowed for getarchitecture to be recursive, and reduced redunancy when
#   it is called throughout the program
# - added ms14-070
#
# v23 2015-01-26
# - typo in --local flag case (pontential vs potential). issue #5 closed. 
#
# v22 2015-01-23
# - speed optimisations! it was too slow beforehand. realised i could easily
#   make it a bit more efficient
# 
# v21 2015-01-22
# - changed display formatting to include nested/linked MS numbers. makes it
#   easier to determine the dependencies
# - made args global
# - changed some code formatting, including double-space instead of \t
# - added some additional comments
# - disable ANSI output if on windows platform 
# - added recent exploits
#
# v20 2014-12-16
# - added ms14-068,ms14-064,ms14-060, and ms14-058 to the internal vuln list
#
# v19 2014-10-08
# - added support for windows server 2012, this includes ignoring the
#   architecture for 2012, and forcing from 32-bit to 64-bit
#
# v18 2014-09-02
# - added ms14-029 poc
#
# v17 2014-08-05
# - fixed a bug where it would not detect OS version when a unicode char comes
#   before search string
#
# v16 2014-07-28
# - improved reading of various file encodings for systeminfo. now attempts to 
#   detect the file first, otherwise loops through common encodings
# - improved OS, service pack, architecture, and release detection. this is now
#   not English-dependent as it was previously
# - better architecture detection of systeminfo input (look for -based string)
# - added /usr/bin/env python
# - added ms14-035 poc
#
# v15 2014-07-15
# - changed file open to io, and attempt to decode as utf-8; otherwise attempt
#   utf-16
#
# v14 2014-07-13
# - allowed for --ostext flag to properly supersede OS detection of systeminfo
#   input
#
# v13a 2014-07-01
# - added new msf flags for ms13-097, and ms14-009
#
# v12a 2014-06-06
# - quick cleanup for release
#
# v11a 2014-05-02
# - fixed the bulletin scrape regex for the update command. ms changed it
#
# v10a 2014-03-24
# - added a hotfixes argument, that can be used to supplement the list
#  of hotfixes detected in the systeminfo input
# - added severity at the end of the output when reporting bulletins
# - added a 'patches' argument, that can be used to determine any
#  of the hotfixes for a specific bulletin. this is good for debugging.
#
# v09a 2014-03-18
# - again, another massive bug on the linked kb searching function
#   getlinkedms(). should be fixed now
# - also checks columns 11 and 12 for superseded, i think it has to
#   do with dos and *nix output
#
# v08a 2014-02-14
# - bug where the superseded column wasn't being checked
#   this may be because it's only xlsx and it parsed differently in csv
# - added some new exploits from edb
#
# v07a 2014-02-12
# - added indicator for os version, and in green
# - better parsing of architecture for itanium based support
#
# v06a 2014-01-19
# - added 'ostext' or 'o' option, when don't have any patch information
#   but just know the OS
#
# v05a
# - added a check for "Kernel version" column, as well as "OS version"
#
# v04a
# - added support for XLSX files directly with the updated XLRD library, this
#   requires the python-xlrd library to be installed and upgraded with:
#   $ pip install xlrd --upgrade
# - changed MS13-101 to E, as there isn't a metasploit module (yet!)
#
# v03a
# - fixed an issue where component KB wasn't being checked
