(*): ISC rating
  • We use 4 levels:
    • PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
    • Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
    • Important: Things where more testing and other measures can help.
    • Less Urt practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
    • The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threatatches.

Seeing that Windows is primarily a GUI-based OS, does anyone actually use telnet on Windows servers? I would ask "does anyone use telnet at all?" but unfortunately my work still uses it for some local-only Unix-based applications.

I doubt Windows users use telnet much. I could see it enabled on systems that run embedded Windows. But the telnet server hasn't been installed by default since Windows 2003. Also the telnet client is usually not installed, minimizing the chances that the server is enabled.

MS15-004 has the MS Exploitability Assessment 0 (Exploitation Detected). Shouldn't ISC rating be changed to Critical or even PATCH NOW ?

MS15-002 is critical with white on red, but the legend reserves that for patch now, no?

I was reviewing Microsoft's summary and saw the same thing. I concur, it should be raised at a minimum for workstations. Internally, we are rating it as critical.

Yes, it hard to believe but Activant (Epicor) uses it for their ERP software working with HVAC and other industries. This was yet another reason their servers at time of departure were only running 2003.

From their site.


How do I use PuTTY with my Eclipse server?

Download and run putty.exe
Enter your server’s Host Name (or IP address)
Select either SSH (preferred, secure, works some AIX servers and all RHEL servers) or Telnet (insecure, works with all Eclipse servers)
Optionally, you may give the session a name and Save for future connections
Select Open to launch the telnet/ssh session
Enter your root login credentials
(AIX only) Set the terminal type:

Wonder if the Edge Transport service for Exchange would be affected, or share DLLs with the Telnet Service since it allows telnet connectivity over TCP port 25 for SMTP.

If that is the case, there will be quite a few Windows boxes with a telnet service installed and running.
