CVE-2023-25946
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 · uneditedAuthentication bypass vulnerability in Qrio Lock (Q-SL2) firmware version 2.0.9 and earlier allows a network-adjacent attacker to analyze the product's communication data and conduct an arbitrary operation under certain conditions.
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 confidenceAuthentication bypass in Qrio Lock Q-SL2 firmware 2.0.9 and earlier allows network-adjacent attackers to analyze communication data and perform arbitrary operations on the smart lock, bypassing authentication controls.

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 lock modelLocate the device documentation, physical label on the lock, or mobile app device info to confirm the model is Qrio Q-SL2Affected if The device is not a Qrio Q-SL2 unit
-
Check the installed firmware versionAccess the Qrio mobile app, check the lock settings panel, or review device documentation to find the current firmware version numberAffected if The firmware version is 2.0.9 or lower (any version <= 2.0.9)
-
Verify network exposureReview the network configuration where the lock is connected. Determine if the lock is accessible on Wi-Fi networks accessible to untrusted or unknown devicesAffected if The lock is reachable by network-adjacent attackers without network segmentation in place
-
Review access logs for unauthorized operationsCheck the Qrio app activity log or any available system logs for lock operations (unlock/lock events) that occurred without user action or from unexpected sourcesAffected if There are unexplained lock operations or authentication anomalies in the logs
You are affected if you have a Qrio Q-SL2 lock running firmware version 2.0.9 or earlier and the device is accessible to network-adjacent attackers.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedUpdate Qrio Lock Q-SL2 firmware to version newer than 2.0.9; as compensating controls, implement network segmentation to limit physical proximity of untrusted devices and monitor for unusual lock activity.
Any firmware version higher than 2.0.9 (e.g., 2.1.0 or later)
- 1. Identify the current firmware version of your Qrio Lock (Q-SL2) device
- 2. Visit the official Qrio support website (qrio.me) or check the Qrio app for firmware updates
- 3. If the current firmware is version 2.0.9 or earlier, download and install the latest available firmware update
- 4. After updating, verify that the firmware version is higher than 2.0.9
- 5. Test that the Qrio Lock functionality remains正常工作 after the update
