Arbitrary File Read:
====================
It is possible to read arbitrary file on the system with root permissions
Proof of Concept:
First instance:
https://host/cgi-bin/mainv2?value=800&showntpclientipinfo=xxx&ntpclientcounterlogfile=/etc/passwd&lcs=xxx
Info-User user is able to read any file on the system with root permissions.
Second instance:
User with Admin-User access is able to read any file on the system via
firmware update functionality. Curl accepts "file" schema which actually
downloads file from the filesystem. Then it is possible to download
/upload/update file which contains content of requested file.
