HDX - IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION & CROSS-SITE REQUEST FORGERY
Poly HDX video endpoints (all models) are subject to multiple cross-site Scripting (XSS) vulnerabilities that could be maliciously abused to gain unauthenticated access to the camera or execute JavaScript in the context of pages viewed by administrators.

Summary
The web interface of HDX endpoints is subject to persistent unauthenticated cross-site scripting using a crafted username with an incoming call, which may allow malicious users to access or control the camera.
A malicious user with administrative privileges can submit diagnostic content that contains embedded JavaScript. Stored XSS occurs when a web application gathers input from a user, and then stores that input for others to potentially retrieve and view. Any administrator who subsequently views the malicious submission will execute the JavaScript in the context of their web browser.
Relevant Common Vulnerabilities and Exposures (CVE) List
Poly would like to thank an Anonymous Security Researcher of Beyond Security’s SecuriTeam Secure Disclosure for reporting the persistent unauthenticated XSS vulnerability to us and for their coordinated disclosure.
Poly would like to thank Vincent Hutsebaut of NCIRC for reporting the stored XSS vulnerabilities to us and for their coordinated disclosure.

Resolution
Poly recommends customers upgrade to firmware build 3.1.10 or later.
For customers who cannot immediately upgrade to a non-vulnerable HDX system software version, the most effect means to mitigate these vulnerabilities is to limit access to the web interface of the HDX to only trusted users, and to limit sources of incoming calls to trusted remote endpoints.
The vulnerable field for the stored XSS is only accessible to HDX administrators via the web. This vulnerability is not triggered through the HDX console, only through the web interface. In addition, we recommend administrators follow standard best practices and change all default passwords and restrict network web access to the HDX unit using firewalls and whitelists.
