Name of the Vulnerable Software and Affected Versions
RouterOS versions prior to 6.49.21
RouterOS versions prior to 7.23.4
RouterOS versions prior to 7.24.2
Description
An issue exists where the SSH server enters the connection protocol following a client-requested rekey without requiring user authentication. This allows an unauthenticated client to open a session channel and send an exec request. The server then dispatches the command, which enables the unauthenticated creation, overwrite, and reconstruction of files within the managed file namespace, including support files that contain diagnostic data and configuration.
Recommendations
Update to version 6.49.21 or later for the Long-term branch.
Update to version 7.23.4 or later for the Long-term branch.
Update to version 7.24.2 or later for the Stable branch.
