接入路由器固件安全分析

Security Analysis of Access Router Firmware

接入路由器作为网络设备的重要组成部分,广泛应用于网络接入用户中。随着网络安全日趋重要,接入路由器作为用户网络访问的重要出口,其安全性影响着用户的数据和隐私信息安全。接入路由器固件包含了路由器的各种功能应用程序和配置参数等信息,固件的漏洞利用使得接入路由器面临被非授权访问修改配置参数、控制利用成为僵尸网络等安全威胁。因此,重点介绍接入路由器固件常见漏洞,主要包括硬件入侵、Web安全以及栈溢出等,并针对各漏洞提出相应的安全建议。

As an important component of network equipment, access router is widely used in among the network access users. As the network security becomes increasingly serious, the access router plays an even more important role in user network access, and its security directly affects the user＇s data and privacy-information security. The firmware of the access router contains information of various functional applications and configuration parameters of the router. The vulnerability of the firmware makes the access router face various cyber security threats, such as accessed by the unauthorized, illegal modification of configuration parameters or controlled and used as a zombie. Therefore, this paper focuses on the common vulnerabilities of access router firmware, including hardware intrusion, Web security and stack overflow, and aiming at various vulerabilities, proposes corresponding security recommendations.
