Philips Hue is vulnerable to a Denial of Service attack. Sending a SYN flood on port tcp/80 will freeze Philips Hue's hub and it will stop responding. The "hub" will stop operating and be frozen until the flood stops. During the flood, the user won't be able to turn on/off the lights, and all of the hub's functionality will be unresponsive. The cloud service also won't work with the hub.

Philips Hue Bridge model 2.X prior to and including version 1935144020 contains a Heap-based Buffer Overflow when handling a long ZCL string during the commissioning phase, resulting in a remote code execution.

Hue 3.12 has XSS via the /pig/save/ name and script parameters.

Open redirect vulnerability in Cloudera HUE before 3.10.0 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the next parameter.

Lack of Transport Encryption in the public API in Philips Hue Bridge BSB002 SW 1707040932 allows remote attackers to read API keys (and consequently bypass the pushlink protection mechanism, and obtain complete control of the connected accessories) by leveraging the ability to sniff HTTP traffic on the local intranet network.

Multiple cross-site scripting (XSS) vulnerabilities in Cloudera HUE 3.9.0 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) First name or (2) Last name field in the HUE Users page.

Cloudera HUE 3.9.0 and earlier allows remote attackers to enumerate user accounts via a request to desktop/api/users/autocomplete.
