QDX 6000 is no longer supported by Poly, and no code updates are planned for fixing these vulnerabilities. Instead, Poly recommends applying the mitigations listed below or updating to a supported product such as Poly Group Series endpoints.



Poly recommends following standard best practices for Unified Communications, as detailed in our best practices paper.

In addition, Poly recommends:

  1. Enabling security mode: This can be done by going to the QDX web UI > admin settings > general settings > check the box for “security mode”, and then clicking on the “update” button.
  2. Disabling web remote access: This can be done by going to the QDX web UI > admin settings > general settings > uncheck the box for “Web” under “Enable Remote Access”, and then clicking the “update” button.

Any customer using an affected system who is concerned about this vulnerability within their deployment should contact Poly Technical Support(888) 248-4143, (916) 928-7561, or visit the Poly Support Site.
