CVE-2018-5767 — AI Deep Analysis Summary

🚨 **Essence**: A critical Input Validation flaw in Tenda AC15 routers. 💥 **Consequences**: Remote attackers can execute arbitrary code via a crafted 'password' parameter in the COOKIE header.…

🛡️ **Root Cause**: Improper Input Validation. Specifically, an **unguarded call to `sscanf`** when parsing the Cookie header for passwords.…

📦 **Affected**: Tenda AC15 (Version 15.03.1.16_multi). 🔄 **Scope**: Also affects other models in the same product line (e.g., AC9) which may not have their own CVEs yet. ⚠️ Check your specific model!

🔓 **Privileges**: Remote Code Execution (RCE). 🕵️ **Data**: Attackers gain full control over the router. They can likely access internal network data, modify settings, and use the router as a pivot point.…

📉 **Threshold**: **LOW**. 🌐 **Auth**: None required (Remote). ⚙️ **Config**: Exploits the standard Cookie header parsing. If the router is online and reachable, it is vulnerable. 🎯 Easy target for automated bots.

💣 **Public Exp?**: **YES**. 📂 **PoC**: Available on GitHub (e.g., db44k/CVE-2018-5767-AC9, Scorpion-Security-Labs). 📜 **Exploit-DB**: ID 44253. 🚨 Wild exploitation is highly likely given the ease of access.

🔍 **Self-Check**: 1. Identify if you use Tenda AC15 (or similar AC-series). 2. Check firmware version (15.03.1.16_multi is vulnerable). 3. Use scanners looking for 'sscanf' vulnerabilities in embedded devices.…

🩹 **Official Fix**: The data implies patches exist or are being addressed (CVE published). 🔄 **Action**: Immediately check Tenda's official website for firmware updates for your specific model.…

🚧 **No Patch?**: 1. **Isolate**: Disconnect the router from the internet if possible. 2. **Network Segmentation**: Place it in a guest network/VLAN to limit lateral movement. 3.…

🔥 **Urgency**: **CRITICAL**. 🚨 **Priority**: **IMMEDIATE ACTION**. RCE vulnerabilities in home routers are high-value targets for botnets. Patch now or isolate immediately. ⏳ Do not delay!
