Title: Security Assessment and Architectural Analysis of the FiberHome SR120A Firmware (2021 Release)
Abstract
The FiberHome SR120A serves as a critical Intelligent Residential Gateway (IRG) in numerous fiber-to-the-home (FTTH) deployments globally. This paper provides a comprehensive technical analysis of the SR120A firmware releases from 2021. By utilizing static analysis and firmware emulation techniques, this study dissects the bootloader chain, kernel configuration, and user-space filesystem hierarchy. Particular attention is paid to the security posture of the device, identifying potential vulnerabilities in the web management interface, the TR-069 client implementation, and the handling of diagnostic tools. The findings suggest that while the 2021 firmware updates addressed legacy backdoors, the device remains susceptible to bin-packing obfuscation and authenticated remote code execution (RCE) vectors due to the reliance on legacy BusyBox versions and hardcoded credentials.
While the 2021 firmware for the FiberHome SR120A offered necessary security and stability patches, it remains a "black box" device for the end-user.
