CVE-2026-2137 — AI Deep Analysis Summary

🚨 **Buffer Overflow in Tenda TX3 SetIpMacBind** - Affects `/goform/SetIpMacBind` endpoint. - **Consequence**: Remote code execution (RCE) via crafted input. - 🧨 Attackers can take full control of the device.

🔍 **Root Cause: CWE-121 (Buffer Overflow)** - Improper input validation in parameter handling. - Function fails to bound-check data before copying into fixed-size buffer. - 📦 Memory corruption leads to arbitrary code exe…

⚠️ **Affected Devices** - **Tenda TX3** routers. - **Versions**: Up to **V16.03.13.11_multi**. - 📦 Component: `SetIpMacBind` in `/goform/`.

🔓 **What Hackers Can Do** - **Gain full remote control** of router. - 📁 Steal sensitive data (config, credentials). - 🧩 Install malware, pivot to internal network. - 🌐 Use device for botnet/DoS attacks.

🔐 **Exploitation Threshold: Low** - **Authentication**: Low privilege (PR:L) required. - **User Interaction**: None needed (UI:N). - 🌐 Attack vector: Remote (AV:N), no special config needed.

💻 **Public Exploit Available** - ✅ PoC exists (GitHub: [IoT-Vuls/tenda/tx3](https://github.com/MRAdera/IoT-Vuls/blob/main/tenda/tx3/fromSetIpMacBind.md)). - 🚨 Exploitation methods are public — likely in the wild.

🔎 **Self-Check Methods** - Scan for **Tenda TX3** devices on network. - Check firmware version: **≤ V16.03.13.11_multi**. - Use tools like **Nmap** or **Shodan** to detect vulnerable endpoints. - 📊 Look for `/goform/SetI…

🛠️ **Official Fix? Unknown** - No patch info provided in data. - 🚫 No official advisory found in references. - ⚠️ May still be vulnerable unless updated.

🛡️ **Workarounds if No Patch** - Disable remote management (HTTP/HTTPS). - 🛑 Block external access to router’s web interface. - Use firewall rules to restrict `/goform/` access. - 🔄 Upgrade firmware if available.

🔥 **Urgency: HIGH** - CVSS: **9.8/10** (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). - 🚨 Remote RCE + public exploit = critical risk. - 💡 **Immediate action recommended** for affected devices.
