Vulnerability Summary
The Poly HDX is susceptible to a command injection vulnerability which allows an authenticated malicious user to execute arbitrary commands on the system when using the firmware update functionality. Poly made changes to the HDX systems starting with the commercial software build 3.1.1.2 to prevent this vulnerability. Input validation was improved so that commands are no longer processed as instructions and the software update will be aborted.
