CVE-2021-3793
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn improper access control vulnerability was reported in some Motorola-branded Binatone Hubble Cameras which could allow an unauthenticated attacker on the same network as the device to access administrative pages that could result in information disclosure or device firmware update with verified firmware.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an improper access control vulnerability in Motorola-branded Binatone Hubble Cameras where administrative web interfaces lack proper authentication, allowing any unauthenticated attacker on the same local network to access sensitive admin pages. This can lead to information disclosure (configuration, credentials, video feeds) and firmware updates using seemingly verified firmware images.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the camera modelLocate the model number on the camera device label or check the Hubble app/device documentation to determine if it is one of: Halo+ Camera, Comfort 85 Connect, Mbp3855, Focus 68, Focus 72r, Cn28, Cn50, or Comfort 40Affected if The device is any of these Binatoneglobal camera models
-
Check the installed firmware versionAccess the camera's web interface (typically at the camera's IP address on the local network) and navigate to Settings > Device Info > Firmware Version, or check via the Hubble mobile app under device settingsAffected if The firmware version is below 03.50.14 for Halo+, below 03.40.02 for Comfort 85 Connect, below 03.40.00 for Mbp3855 or Focus 72r, or any version for Focus 68, Cn28, Cn50, or Comfort 40
-
Verify the admin web interface is network-accessibleConfirm the camera is connected to the local network and accessible via HTTP/HTTPS on its IP address (common ports 80, 443, or 8080)Affected if The admin web interface responds to HTTP requests from other devices on the local network
-
Test for unauthenticated admin accessAttempt to access common admin paths such as /admin, /settings, /config, or /device.html without providing any login credentialsAffected if The admin pages load and display sensitive information (configuration, credentials, firmware update options) or allow firmware upload without requiring any authentication
The device is affected if it is a Binatoneglobal Halo+, Comfort 85 Connect, Mbp3855, Focus 68, Focus 72r, Cn28, Cn50, or Comfort 40 camera with a firmware version in the affected range AND the admin web interface is accessible without authentication on the local network

dbcve · scoped03.40.0003.40.0203.50.14
Isolate affected camera devices on a dedicated VLAN or network segment to limit attack surface, implement network access controls restricting administrative interface access to authorized management stations only, and check manufacturer for firmware updates.
Upgrade to specific fixed firmware versions: Halo+ to 03.50.14, Comfort 85 Connect to 03.40.02, Mbp3855 to 03.40.00, Focus 72r to 03.40.00
- 1. Identify the exact model of your Motorola/Binatone Hubble camera from the affected product list
- 2. For Halo+ Camera: upgrade firmware to version 03.50.14 or later
- 3. For Comfort 85 Connect: upgrade firmware to version 03.40.02 or later
- 4. For Mbp3855: upgrade firmware to version 03.40.00 or later
- 5. For Focus 72r: upgrade firmware to version 03.40.00 or later
- 6. For Focus 68, Cn28, Cn50, and Comfort 40: no fixed firmware version is available; apply network segmentation to isolate these devices
- 7. Implement network segmentation (VLAN) to isolate camera devices from untrusted networks
- 8. Place affected devices behind a firewall and restrict access to trusted IP addresses only
