**TOTOlink N600R V5.3c.7159\_B20190425 Command injection vulnerability****Overview**

*   Manufacturer's website information：http://www.totolink.cn
*   Firmware download address ： http://www.totolink.cn/home/menu/detail.html?menu\_listtpl=download&id=2&ids=36

**1\. Affected version**

Figure 1 shows the latest firmware Ba of the router

**Vulnerability details**

The program passes the contents obtained by the filename parameter to V8

Then, format the matching content of V8 through the sprintf function into V31, and bring V31 into the cstesystem function

At this time, corresponding to the parameter A1, the function assigns A1 to the array of V9, and finally executes the command through the execv function. There is a command injection vulnerability

**Recurring vulnerabilities and POC**

In order to reproduce the vulnerability, the following steps can be followed:

1.  Use the fat simulation firmware V5.3c.7159\_B20190425
2.  Attack with the following POC attacks

    POST /cgi-bin/cstecgi.cgi HTTP/1.1
