CVE-2025-11418 — AI Deep Analysis Summary

🚨 **Essence**: Tenda CH22 suffers from a **Stack-based Buffer Overflow** (CWE-121). 📉 **Consequences**: Attackers can execute arbitrary code, leading to full system compromise. The CVSS score is **9.8 (Critical)**! 💥

🛡️ **Root Cause**: Flaw in `/goform/AdvSetWrlsafeset`. Specifically, the parameter `mit_ssid_index` is handled incorrectly. ❌ This allows writing beyond buffer limits, corrupting the stack. 🧠

🎯 **Affected**: Tenda CH22 Router. 📦 **Version**: 1.0.0.1 and **earlier** versions. If you are on this version, you are vulnerable! ⚠️

💻 **Impact**: High! CVSS shows **C:H, I:H, A:H**. Hackers can steal sensitive data, modify configurations, and crash the device. Full control is likely possible. 🔓

🔓 **Threshold**: **LOW**. CVSS vector `AV:N/AC:L/PR:N/UI:N`. No authentication (PR:N) or user interaction (UI:N) needed. Remote exploitation is easy! 🚀

🕵️ **Exploit Status**: No official PoC in the data. However, GitHub issues and VDB entries exist. Wild exploitation is **possible** but unconfirmed. Be cautious! 🧐

🔍 **Self-Check**: Scan for open HTTP ports on Tenda CH22 devices. Check firmware version. Look for requests to `/goform/AdvSetWrlsafeset`. 📡

🔄 **Fix**: The data does **not** list a specific patch link. Check Tenda's official site (tenda.com.cn) for updates. 🏢 If no patch, assume vulnerable.

🛑 **Workaround**: If unpatched, **disable remote management**. Restrict access to LAN only. Change default passwords. Monitor logs for suspicious `/goform` requests. 🚧

⚡ **Urgency**: **CRITICAL**. CVSS 9.8 + No Auth required = Immediate action needed. Patch or isolate the device NOW! 🏃‍♂️💨
