Security readout for executives and security teams
Plain-English summary
The Hickory Smart Android app logged sensitive smart-lock communications to a file on ordinary device storage. A person or app with local access to the Android device could read this without rooting the phone, creating a confidentiality risk around lock/API and BLE communication data.
Executive priority
Treat as a targeted confidentiality issue for organizations still using these locks. It is not internet-remote by itself, but exposed lock communication data on a phone can become operationally sensitive if devices are shared, lost, or accessed by untrusted apps.
Technical view
CVE-2019-5634 is CWE-532 sensitive information in log files affecting Hickory Smart for Android version 01.01.43 and prior. The app stored internet API and BLE lock communication details in HickorySmartLog/Logs/SRDeviceLog.txt on default USB or SDcard storage paths accessible without root.
Likely exposure
Exposure is likely limited to Android devices running Hickory Smart version 01.01.43 or earlier, especially where device storage is accessible to other local apps, USB access, or people handling the device.
Exploitation context
The CVE is not listed in KEV, and the provided sources do not state active exploitation. The attack model is local access with low complexity and low privileges, focused on confidentiality rather than integrity or availability.
Researcher notes
Evidence supports insecure local logging, not code execution or remote compromise. The source bundle does not identify a specific patch version or vendor mitigation, so remediation should be validated against current vendor guidance rather than assumed.
Mitigation direction
- Inventory Android devices using Hickory Smart.
- Check installed app versions for 01.01.43 or earlier.
- Check Belwith or Google Play guidance for updated software.
- Remove affected app logs from device storage where authorized.
- Restrict device access until vendor guidance is confirmed.
Validation and detection
- Confirm whether Hickory Smart is installed on Android devices.
- Verify app version against 01.01.43 and prior.
- Check authorized devices for HickorySmartLog/Logs/SRDeviceLog.txt.
- Review whether logs contain sensitive API or BLE communications.
- Confirm affected logs are removed after remediation.

Insertion of Sensitive Information into Log File
Insertion of Sensitive Information into Log File represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
