A missing double-check feature in the WebGUI for CLI deactivation in Infinera G42
version R6.1.3 allows an authenticated administrator to make other
management interfaces unavailable via local and network interfaces. The CLI deactivation via the WebGUI does not only stop CLI interface but deactivates also Linux Shell, WebGUI and Physical Serial Console access. No
confirmation is asked at deactivation time. Loosing access to these services device administrators are at risk of completely loosing device control.

Lack or insufficent input validation in WebGUI CLI web in Infinera G42
version R6.1.3 allows remote authenticated users to read all OS files
via crafted CLI commands.
Details: The web interface based management of the Infinera G42 appliance enables the feature of
executing a restricted set of commands. This feature
also offers the option to execute a script-file already present on the target
device. When a non-script or incorrect file is specified, the content
of the file is shown along with an error message. Due to an execution of the http service with a privileged user all files on the file system can be viewed this way.

Unrestricted access to OS file system in SFTP service in Infinera G42
version R6.1.3 allows remote authenticated users to read/write OS files
via SFTP connections.
Details: Account members of the Network Administrator profile can access the
target machine via SFTP with the same credentials used for SSH CLI
access and are able to read all files according to the OS permission instead of remaining inside the chrooted directory position.

The misconfiguration in the sudoers configuration of the operating system in
Infinera G42 version R6.1.3 allows low privileged OS users to
read/write physical memory via devmem command line tool.
This could
allow sensitive information disclosure, denial of service, and privilege
escalation by tampering with kernel memory.
Details: The output of "sudo -l" reports the presence of "devmem" command
executable as super user without using a password. This command allows
to read and write an arbitrary memory area of the target device,
specifying an absolute address.
