BlindElephant Web Application Fingerprinter (original) (raw)

The BlindElephant Web Application Fingerprinter attempts to discover the version of a (known) web application by comparing static files at known locations against precomputed hashes for versions of those files in all all available releases. The technique is fast, low-bandwidth, non-invasive, generic, and highly automatable.

Getting Started

BlindElephant can be used directly as a tool on the command line, or as a library to provide fingerprinting functionality to another program.

Pre-requisites:

Get the code:

Installation:

Installation is only required if you plan to use BlindElephant as a library. Make sure that your python installation has distutils, and then do:cd blindelephant/src sudo python setup.py install(Windows users, omit sudo)

Example Usage (Command Line):

setup.py will have placed BlindElephant.py in your /usr/local/bin dir.

$ BlindElephant.py Usage: BlindElephant.py [options] url appName

Options: -h, --help show this help message and exit -p PLUGINNAME, --pluginName=PLUGINNAME Fingerprint version of plugin (should apply to web app given in appname) -s, --skip Skip fingerprinting webpp, just fingerprint plugin -n NUMPROBES, --numProbes=NUMPROBES Number of files to fetch (more may increase accuracy). Default: 15 -w, --winnow If more than one version are returned, use winnowing to attempt to narrow it down (up to numProbes additional requests). -l, --list List supported webapps and plugins

Use "guess" as app or plugin name to attempt to attempt to discover which supported apps/plugins are installed.

$ python BlindElephant.py http://laws.qualys.com movabletype Loaded /usr/local/lib/python2.6/dist-packages/blindelephant/dbs/movabletype.pkl with 96 versions, 2229 differentiating paths, and 209 version groups. Starting BlindElephant fingerprint for version of movabletype at http://laws.qualys.com

Fingerprinting resulted in: 4.22-en 4.22-en-COM 4.23-en 4.23-en-COM

Best Guess: 4.23-en-COM

Example Usage (Library):

$python

from blindelephant.Fingerprinters import WebAppFingerprinter

#Construct the fingerprinter #use default logger pointing to console; can pass "logger" arg to change output fp = WebAppFingerprinter("http://laws.qualys.com", "movabletype") #do the fingerprint; data becomes available as instance vars fp.fingerprint() (same as above) print "Possible versions:", fp.ver_list Possible versions: [LooseVersion ('4.22-en'), LooseVersion ('4.22-en-COM'), LooseVersion ('4.23-en'), LooseVersion ('4.23-en-COM')] print "Max possible version: ", fp.best_guess Max possible version: 4.23-en-COM
