| Title | TOTOLINK X18 Wireless Device V9.1.0cu.2024_B20220329 Remote Code Execution (RCE) |
|---|
| Description | A remote command execution (RCE) vulnerability exists in the X18 Wireless Device firmware. The `mtkhnatEnable` parameter is directly executed in the system without proper sanitization, leading to arbitrary command execution.
- **Vulnerable Function**: `sub_410C80` in binary embedded servers
- **Affected Component**: `Cstecgi.cgi`
- **Root Cause**: User-controlled `mtkhnatEnable` parameter is passed to `dosystem $a3`, which executes arbitrary system commands.
### **Impact**
An attacker can execute arbitrary system commands, gaining full control over the device, potentially leading to:
- Full system compromise
- Unauthorized access to network resources
- Deployment of persistent backdoors |
