Improper File Access in Infinera G42

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.
