CVE-2022-3007
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 · uneditedThe vulnerability exists in Syska SW100 Smartwatch due to an improper implementation and/or configuration of Nordic Device Firmware Update (DFU) which is used for performing Over-The-Air (OTA) firmware updates on the Bluetooth Low Energy (BLE) devices. An unauthenticated attacker could exploit this vulnerability by setting arbitrary values to handle on the vulnerable device over Bluetooth. Successful exploitation of this vulnerability could allow the attacker to perform firmware update, device reboot or data manipulation on the target device.
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 confidenceThe Syska SW100 Smartwatch contains an improperly implemented Nordic Device Firmware Update (DFU) mechanism for BLE OTA updates. The vulnerability allows unauthenticated attackers to write arbitrary values to BLE handles, enabling firmware manipulation, device reboot, or data tampering over Bluetooth without authentication.

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.
-
Confirm device modelInspect the smartwatch body, packaging, or companion app settings to verify the device is a Syska SW100 SmartwatchAffected if The device is a Syska SW100 Smartwatch
-
Check firmware versionAccess the smartwatch settings (typically under About or Device Info) or the companion mobile app to retrieve the installed firmware version numberAffected if Firmware version is 2.0 or lower (any version <= 2.0)
-
Verify Bluetooth is activeCheck the smartwatch Bluetooth settings or status bar to determine if BLE is currently enabledAffected if Bluetooth is turned on and the device is discoverable or paired
-
Inspect Nordic DFU service exposureUse a BLE scanner or BLE debugging tool (such as nRF Connect or similar) to enumerate GATT services and check for the Nordic DFU service with writable characteristics that do not require authenticationAffected if The Nordic DFU service/characteristic is present and accepts unauthenticated write operations
A user is affected if they own a Syska SW100 Smartwatch running firmware version 2.0 or lower with Bluetooth enabled and the Nordic DFU service is exposed without authentication requirements.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply any vendor-supplied firmware update for the Syska SW100 that addresses this DFU authentication flaw; as an interim control, disable Bluetooth when not in use to reduce attack surface.
