This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Philips Hue Bridge. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the configuration of the SRP authentication mechanism in the HomeKit Accessory Protocol service, which listens on TCP port 8080 by default.
