Philips Hue Bridge hap_pair_verify_handler Sub-TLV Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Philips Hue Bridge. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the hap_pair_verify_handler function of the hk_hap service, which listens on TCP port 8080 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-28337.
AnalysisAI
Heap-based buffer overflow vulnerability in Philips Hue Bridge devices that allows network-adjacent attackers with authentication (which can be bypassed) to achieve remote code execution as root. The vulnerability affects the HomeKit Accessory Protocol (HAP) implementation on TCP port 8080 and has a high CVSS score of 8.0, though no active exploitation or public PoC has been reported.

RemediationAI
Within 24 hours: Inventory all Philips Hue Bridge deployments and document network connectivity; isolate affected devices to a dedicated VLAN if possible. Within 7 days: Implement network access controls restricting TCP port 8080 to authorized users only; disable HomeKit Accessory Protocol if not actively required; establish monitoring for suspicious activity on port 8080. …
