The ZTE F609 XPON (Passive Optical Network) is a widely deployed Fiber-to-the-Home (FTTH) gateway, particularly in Southeast Asia, the Middle East, and South America. Despite its prevalence, the device is known to harbor multiple firmware-level vulnerabilities. This paper provides a forensic analysis of the ZTE F609 firmware (versions V9 and V10), examining its filesystem architecture, boot process, known CVE vulnerabilities, and extraction methodologies. We identify critical issues including hardcoded credentials, command injection points, and lack of signature verification. Finally, we propose mitigation strategies for ISPs and end-users.
The is a versatile Optical Network Terminal (ONT) frequently used in FTTH (Fiber to the Home) setups. When looking into "XPON" firmware for this device, it typically refers to a "dual-mode" capability that allows the device to operate on both GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network) infrastructures .
