Openssh 7.7



Summary

Multiple NetApp products incorporate OpenSSH. OpenSSH versions 7.7 through 7.9 and 8.x before 8.1 are susceptible to a vulnerability which when successfully exploited could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS).

We use OpenSSH(7.7 & 8.1) OS: Windows Server 2019 Standard. From time to time, the service hangs - although the state of the service is running (in service management), it stops listening on port 22. In some cases, when trying to connect using telnet, we get a 'black screen' without the local version string.

Impact

  • SSH (Secure Shell) is a protocol which facilitates secure communications between two systems using a client-server architecture and allows users to log in to server host systems remotely. Unlike other remote communication protocols, such as FTP or Telnet, SSH encrypts the login session, rendering the connection difficult for intruders to collect unencrypted passwords.
  • OpenSSH 7.7/7.7p1 (2018-04-02) OpenSSH 7.7 was released on 2018-04-02. It is available from the mirrors listed at OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support.

Successful exploitation of this vulnerability could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS).

OpenSSH is the open-source version of the Secure Shell (SSH) tools used by administrators of Linux and other non-Windows for cross-platform management of remote systems.OpenSSH has been added to Windows as of autumn 2018, and is included in Windows 10 and Windows Server 2019.

SSH is based on a client-server architecture where the system the user is working on is the client and the remote system being managed is the server.OpenSSH includes a range of components and tools designed to provide a secure and straightforward approach to remote system administration, including:

  • sshd.exe, which is the SSH server component that must be running on the system being managed remotely
  • ssh.exe, which is the SSH client component that runs on the user's local system
  • ssh-keygen.exe generates, manages and converts authentication keys for SSH
  • ssh-agent.exe stores private keys used for public key authentication
  • ssh-add.exe adds private keys to the list allowed by the server
  • ssh-keyscan.exe aids in collecting the public SSH host keys from a number of hosts
  • sftp.exe is the service that provides the Secure File Transfer Protocol, and runs over SSH
  • scp.exe is a file copy utility that runs on SSH

Documentation in this section focuses on how OpenSSH is used on Windows, including installation, and Windows-specific configuration and use cases. Here are the topics:

Additional detailed documentation for common OpenSSH features is available online at OpenSSH.com.

The master OpenSSH open source project is managed by developers at the OpenBSD Project.The Microsoft fork of this project is in GitHub.Feedback on Windows OpenSSH is welcomed and can be provided by creating GitHub issues in our OpenSSH GitHub repo.
