Philips Hue Bridge HomeKit Pair-Setup Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability

Philips Hue Bridge HomeKit Pair-Setup 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. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the hk_hap_pair_storage_put function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the HomeKit service.

Was ZDI-CAN-28326.
