CVE-2017-16564
Stored Cross-site scripting (XSS) vulnerability in /cgi-bin/config2 on Vonage (Grandstream) HT802 devices allows remote authenticated users to inject arbitrary web script or HTML via the DHCP vendor class ID field (P148).
Does this matter?
Lower severity and a low EPSS score (0.61%). Track it; it rarely justifies an emergency change on its own.
