Summary ======= The operating system used by Pexip Infinity does not create unique SSH host keys on deployment of new Management and Conferencing Nodes, using fixed host keys instead. Host keys are used to verify the identity of the remote host when connecting to it over SSH. These keys are contained in the publicly available software image. An attacker with privileged network access may make use of these keys to spoof the identity of a Pexip Infinity installation or conduct man-in-the-middle attacks on administrative SSH sessions. This may permit the attacker access to credentials used to authenticate sessions over SSH and provide shell access to the affected systems. This issue is resolved in Pexip Infinity version 8.
