Summary

The Z80Ultra (NX741J) product contains a vulnerability where non-privileged programs can retrieve the Wi-Fi MAC address by querying the read-only field factory_mac_address in the Settings.Secure database. This field is not properly protected from access by unprivileged applications.

Risk Assessment

Unauthorized access to the Wi-Fi MAC address can enable device tracking and correlation with other network data. This may violate user privacy and be exploited for targeted attacks.

Recommendation

Update Z80Ultra (NX741J) software to a version containing the fix, if available. If not, restrict unprivileged application access to the Settings.Secure database or consider retiring the device from high-confidentiality environments.
