Cloud API reachable over the internet (AV:N), requires only a low-privilege self-registered account (PR:L), no victim interaction (UI:N), and full takeover of device data and control yields C/I/A:H.

Lifecycle Timeline
1DescriptionCVE.org
A flaw in Naxclow's platform’s onboarding workflow allows an attacker to replay a confirm-then-bind sequence to silently reassign a device to an arbitrary account. Because the affected endpoints validate request signatures but do not confirm legitimate ownership, an attacker with any account can take over a device without user interaction while the device remains online and unaware.
AnalysisAI
Device takeover in Naxclow's IoT platform (Smart Doorbell X3, X Smart Home, V720, and iX Cam) allows any authenticated attacker to silently reassign victim devices to their own account by replaying the onboarding confirm-then-bind sequence. The affected endpoints validate request signatures but never verify legitimate ownership, enabling remote hijacking without user interaction or device-side awareness. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Attacker needs (1) a valid Naxclow platform account (PR:L - any self-registered account qualifies) and (2) the ability to issue the platform's confirm-then-bind API call against a target device identifier with a correctly signed request body; legitimate ownership of that device is NOT required because the endpoint only validates the request signature, not the account-to-device authorization. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 4.0 vector AV:N/AC:L/AT:N/PR:L/UI:N with VC:H/VI:H/VA:H (base 8.7) reflects a network-reachable, low-complexity bug usable by any account holder with no victim interaction - a realistic profile for cloud IoT abuse. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a free Naxclow account, captures or replays the confirm-then-bind API sequence for a target device ID (which may be enumerated or harvested), and submits a valid-signature bind request that reassigns the doorbell or camera to their account. The victim's app silently loses the device while the camera continues streaming - now to the attacker - without the device itself indicating a re-pairing event. … |
| Remediation | No vendor-released patch identified at time of analysis in the supplied intelligence; consult CISA ICSA-26-162-02 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-162-02) for current vendor guidance and any fixed platform release. … Detailed patch versions, workarounds, and compensating controls in full report. |
