At its heart, the ZXHN H108L firmware is a heavily customized Linux distribution, typically built around a 2.6.x kernel. Due to licensing obligations under the GNU General Public License (GPL), ZTE has released portions of the source code, revealing a system reliant on BusyBox—a software suite that provides several Unix utilities in a single executable to minimize storage footprint. The firmware is structured into several key partitions stored on the device’s parallel NOR flash memory: a bootloader (CFE - Common Firmware Environment), a kernel image, a root filesystem (usually SquashFS for compression and read-only integrity), and a configuration partition (often called "param" or "nvram").
老设备最令人担忧的问题并非性能，而是安全。ZXHN H108L 历史上被发现存在多个高危安全漏洞，其中最著名的是 CVE-2014-8493 。该漏洞允许远程攻击者通过向 Forms/access_cwmp_1 发送精心构造的请求，修改设备的 CWMP（即 TR-069 远程管理协议）配置，从而获得对设备的未授权访问。更严重的是，攻击者无需任何身份认证即可利用此漏洞。此外，中兴曾在 2014 年发布安全公告，确认 ZXV10 H108L V1.0 存在堆栈缓冲区溢出漏洞（heap-based buffer overflow），可能被利用执行任意代码。
