HDX - EXECUTION WITH UNNECESSARY PRIVILEGES

The Poly HDX Command Shell is susceptible to an escalation of privileges vulnerability that could lead to unauthorized system access and information disclosure. Poly made changes to the HDX software starting with the commercial software build 3.1.1.2 to prevent this vulnerability by removing access to development modes and adding additional restrictions on what commands could be issued.
