# Vulnerability Type: Path Traversal

CVSS v3: 6.5  
CVSS vector: 3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N  
CWE: CWE-22

Vulnerability description: An issue was discovered in EasyPHP Webserver  
14.1. An Absolute Path Traversal vulnerability in / allows remote users to  
bypass intended SecurityManager restrictions and download any file if you  
have adequate permissions outside the documentroot configured on the server.

Proof of concept:

EasyPHP Webserver 14.1 Path Traversal / Remote Code Execution

TOTOLINK A7100RU V7.4cu.2313_B20191024 has a Command Injection vulnerability. An attacker can obtain a stable root shell through a specially constructed payload.

**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**

程序通过获取参数internetPri中的内容传递给v20，之后将v20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

**POC**

复现结果如下

图2 POC攻击效果

最后，您可以编写exp，这可以实现获得根shell的非常稳定的效果
