CVE detail

CVE-2026-3557

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.

Potential internet exposure

Potential exposure only — not proof of vulnerability.Shodan results indicate potentially internet-exposed products, not confirmed vulnerable systems. They do not confirm that any returned system is vulnerable to CVE-2026-3557.

Product-level CPE searches intentionally omit version fields and NVD version-range or configuration certainty. Verify the exact product version and configuration independently.

Sign-in required. Shodan requires you to sign in to run these filter searches.

How this vector reads

CVSS 3.0 base metrics decoded below. This explanation does not recalculate or change the NVD score.

Attack Vector (AV): Adjacent. The attacker must reach the same or an adjacent network.
Attack Complexity (AC): Low. No special conditions beyond the attacker-controlled steps are required.
Privileges Required (PR): Low. The attacker needs basic user-level privileges.
User Interaction (UI): None. Exploitation does not require another user to act.
Scope (S): Unchanged. Impacts remain within the vulnerable security authority.
Confidentiality Impact (C): High. There is a total or serious impact to this security property.
Integrity Impact (I): High. There is a total or serious impact to this security property.
Availability Impact (A): High. There is a total or serious impact to this security property.
