Submit #754669: Totolink X18 router V9.1.0cu.2053_B20230309 Command Injectioninfo

TitleTotolink X18 router V9.1.0cu.2053_B20230309 Command Injection
DescriptionA command injection vulnerability has been discovered in the TOTOLINK X18 Router. Attackers can exploit this vulnerability to execute arbitrary commands by sending malicious HTTP POST packets. The vulnerability is triggered when the request path is `/cgi-bin/cstecgi.cgi`, requiring login to obtain a `token`. The trigger point is located in the `sub_41080C` method of the `cstecgi.cgi` component. Here, the `pid` field is not validated and is directly appended to `kill %s`, and then the `CsteSystem` method is used to execute the command.
