G42

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.

The target device exposes a service on a specific TCP port with a configured endpoint. The access to that endpoint is granted using a Basic Authentication method. The endpoint accepts also the PUT method and it is possible to write files on the target device file system. Files are written as root. Using Postman it is possible to perform a Directory Traversal attack and write files into any location of the device file system. Similarly to the PUT method, it is possible to leverage the same mechanism to read any file from the file system by using the GET method.

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.

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.

A path traversal vulnerability of the WebGUI HTTP endpoint in Infinera G42 version R6.1.3 allows remote authenticated users to download all OS files via HTTP requests. Details: Lack or insufficient validation of user-supplied input allows authenticated users to access all files on the target machine file system that are readable to the user account used to run the httpd service.
