A vulnerability has been discovered in OpenSSH which could allow for authentication bypass. OpenSSH (Open Secdure Shell) is an open-source suite of secure networking utilities based on the SSH protocol. It provides encrypted communication sessions over unsecured networks in a client-server architecture, primarily used for remote login and secure file transfers. Successful exploitation of the vulnerability could provide an attacker with root access to all the servers an organization has, if the vulnerable protocol runs on them.
