Unauthenticated SPI Flash Firmware Extraction in Meitrack T366G-L GPS Tracker

IdentifiersCVE-2025-51643CWE-1191

CVE-2025-51643 affects Meitrack T366G-L GPS tracker devices. The device's onboard SPI flash chip, identified as a Winbond 25Q64JVSIQ, is accessible without authentication, encryption, or tamper protection. An attacker with physical access to the hardware can attach a standard SPI programmer and use tooling such as flashrom to read out the contents of the flash directly. Successful extraction of the firmware and stored data can expose sensitive configuration information, including APN credentials, backend server information, and other network parameters. The issue is a hardware/firmware protection weakness in which sensitive data stored in non-volatile memory is not adequately protected against direct physical access.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An attacker with physical possession of or direct access to the device can extract firmware and recover sensitive operational configuration data. Exposed information may include APN credentials, backend server endpoints, and network parameters, which can facilitate further compromise of the tracked environment, cloning or reverse engineering of the device configuration, infrastructure mapping, and potential follow-on attacks against associated backend services or mobile/network accounts. The vulnerability primarily results in confidentiality loss of firmware and stored secrets.

Mitigation

If you can’t patch tonight, do this now.

Restrict physical access to affected Meitrack T366G-L devices and maintain chain-of-custody controls for deployed units. Assume that any device that has been lost, stolen, serviced by untrusted parties, or otherwise physically exposed may have had its flash contents extracted. Rotate APN credentials and any backend-related secrets stored on the device, monitor backend systems for unauthorized use of recovered configuration data, and segment or limit backend trust placed in device-stored credentials. Where feasible, add physical tamper seals or enclosure protections to increase the difficulty of direct flash access.

Remediation

Patch, then assume compromise.

Implement hardware and firmware protections for non-volatile storage. This includes enabling available readout-protection or memory-protection features where supported, encrypting sensitive data at rest in flash, minimizing storage of plaintext credentials on the device, and redesigning the platform to incorporate tamper resistance or tamper-evident controls around debug/programming access to the SPI flash. If a product update is available from the vendor, apply the vendor-provided remediation. Rotate any credentials or secrets that may have been stored on affected devices and treat extracted configuration data as compromised.
