CVE-2026-86551 is a low-severity vulnerability in the ZTE NX741J (Z80Ultra) device where non-privileged applications can access the Wi-Fi MAC address by reading the factory_mac_address field in the Settings.Secure database. This exposure is classified under CWE-668, indicating resource exposure to an unintended sphere. The vulnerability does not allow modification or denial of service and requires local access with user interaction.
AI Analysis
Technical Summary
The ZTE NX741J device contains a vulnerability (CVE-2026-86551) where non-privileged programs can retrieve the Wi-Fi MAC address by querying a read-only field named factory_mac_address in the Settings.Secure database. This constitutes an exposure of a resource to an unintended sphere (CWE-668). The CVSS 3.1 score is 3.3, reflecting low impact with local attack vector, low complexity, no privileges required, and user interaction needed. Confidentiality impact is limited to partial information disclosure (Wi-Fi MAC address), with no impact on integrity or availability.
Potential Impact
The vulnerability allows unauthorized local applications to access the device's Wi-Fi MAC address, potentially aiding in device tracking or fingerprinting. There is no impact on data integrity or availability. The exposure is limited to information disclosure of a non-sensitive but device-unique identifier.
Mitigation Recommendations
No vendor advisory or patch information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit installation of untrusted applications and restrict local access to the device where possible.
