The Tenda AC8 is a popular budget Wi-Fi router. Because Tenda frequently revises hardware versions (v1, v2, v4, etc.) and changes chipset manufacturers (Broadcom vs. Realtek), a "one size fits all" firmware guide is impossible.

Below is a solid write-up regarding the Tenda AC8 firmware ecosystem, covering versions, troubleshooting common issues, and the security landscape.

Issue 1: "The file is invalid" or "Firmware mismatch"

Cause: You downloaded the wrong hardware version (e.g., v2 firmware for a v1 router). Solution: Double-check your sticker. Download the correct file. If you are sure it is correct, clear your browser cache or try a different browser (Firefox or Chrome).

A. Command Injection Vulnerabilities (CVE-2020-10987)

The most significant vulnerability affecting the AC8 (and other Tenda models) is a command injection flaw.

Mechanism: The web interface fails to sanitize user input in specific POST parameters (e.g., the deviceID parameter in the formWriteDeviceID function).
Exploit: An attacker can send a crafted HTTP request containing shell metacharacters (like ; or |). The firmware passes this input directly to a system() call without filtering.
Impact: Remote Code Execution (RCE) with root privileges. An attacker can effectively take full control of the router.

How to Identify Your Current Tenda AC8 Firmware Version

Before downloading anything, you must know what version you currently have. Installing the wrong firmware (e.g., hardware V1 vs V2) will brick your router.

Step-by-step check:

Connect your PC to the Tenda AC8 (Wi-Fi or Ethernet).
Open a browser and navigate to 192.168.0.1 (or tendawifi.com).
Login (default credentials: admin/admin).
Navigate to System Tools > Firmware Upgrade.
Look for the Current Firmware Version (e.g., V15.03.06.51_multi).

Hardware Version: Flip the router over. Look for a sticker that says "Ver: 1.0" or "Ver: 2.0". You must match the firmware to this hardware version.
