CVE-2025-51643
LowCVSS 2.4Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
Meitrack T366G-L GPS Tracker devices contain an SPI flash chip (Winbond 25Q64JVSIQ) accessible without authentication or tamper protection. An attacker with physical access can use a standard SPI programmer and flashrom to extract the firmware. This exposes sensitive configuration data such as APN credentials, backend server information, and network parameters.
Risk Assessment
Physical access to the device allows leakage of credentials and network configuration, potentially enabling communication interception or device impersonation. The risk mainly affects devices deployed in public or unprotected locations.
Recommendation
Physically secure devices against unauthorized access and consider encrypting configuration data stored in flash. Rotate APN credentials and monitor for unusual network activity.
