Description:
The Crestron AirMedia AM-100 with firmware versions v1.1.1.11 - v1.2.1 is vulnerable to multiple issues.

1) Path Traversal

GET request: 
http://[AM-100-ADDRESS]/cgi-bin/login.cgi?lang=en&src=../../../../../../../../../../../../../../../../../../../../etc/shadow

2) Hidden Management Console

http://[AM-100-ADDRESS]/cgi-bin/login_rdtool.cgi
The AM-100 has a hardcoded default credential of rdtool::mistral5885
This interface contains the ability to upload arbitrary files (RD upload) and can enable a telnet server that runs on port 5885 (RD Debug mode).

3) Hardcoded credentials

The default root password for these devices is root::awind5885
Valid login sessions for the default (non-debugging) management interface are stored on the filesystem as session01, session02.. etc. Cleartext credentials can be read directly from these files.
