The SSH server running on the remote host is affected by a file creation restriction bypass vulnerability. Description According to its banner, the version of OpenSSH running on the remote host is prior to 7.6. It is, therefore, affected by a file creation restriction bypass vulnerability related to the 'processopen' function in the file 'sftp. 2017-11-06 - Jakub Jelen - 7.4p1-15 + 0.10.3-2 - Do not hang if SSH AuthorizedKeysCommand output is too large (#1496467) - Do not segfault pamsshagentauth if keyfile is missing (#1494268) - Do not segfault in audit code during cleanup (#1488083) - Add WinSCP 5.10+ compatibility (#1496808) - Clatch between ClientAlive.

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
