Lifecycle Timeline
1DescriptionCVE.org
Naxclow device identifiers use fixed manufacturing prefixes combined with sequential counters, producing a fully predictable and enumerable identifier space. Because the platform also exposes an endpoint that reveals the current identifier high-water mark, the active fleet can be enumerated.
AnalysisAI
Device identifier enumeration across Naxclow's IoT product line - including the Smart Doorbell X3, X Smart Home platform, V720, and IX Cam - allows unauthenticated remote attackers to build a complete inventory of active devices deployed in the field. The identifier scheme combines fixed manufacturing prefixes with sequential counters (CWE-340), and the platform compounds this by exposing an endpoint that reveals the current identifier high-water mark, effectively handing attackers a starting point for a full sweep. …

Vulnerability AssessmentAI
| Exploitation | No authentication is required (CVSS PR:N) and no special client configuration is needed (AC:L, AT:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 with vector AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N reflects a remotely exploitable, zero-authentication, low-complexity information disclosure flaw with limited confidentiality impact (device identifiers, not credentials or PII directly). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends a single HTTP request to the Naxclow platform's public identifier high-water mark endpoint to determine the current maximum device ID, then iterates sequentially through the predictable prefix+counter ID space to enumerate every active device in the fleet. The resulting device inventory reveals which physical locations have deployed Naxclow cameras and doorbells, enabling targeted follow-on attacks such as physical intrusion timing or device-specific exploitation. … |
| Remediation | No vendor-released patch version has been identified at time of analysis; the CPE entries carry wildcard version ranges and no fixed-version advisory was referenced. … Detailed patch versions, workarounds, and compensating controls in full report. |
