CVE-2025-10432 — AI Deep Analysis Summary

Q: What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: A stack-based buffer overflow in Tenda AC1206. 💥 **Consequences**: Remote Code Execution (RCE), full system compromise, and data theft due to memory corruption.

Q: Root Cause? (CWE/Flaw)

🛠️ **CWE**: CWE-121 (Stack-based Buffer Overflow). 🐛 **Flaw**: The `check_param_changed` function in `/goform/AdvSetMacMtuWa` mishandles the `wanMTU` parameter, allowing buffer overflow.

Q: Who is affected? (Versions/Components)

📦 **Vendor**: Tenda. 📱 **Product**: AC1206 Wireless Gigabit Router. 📅 **Version**: Specifically **15.03.06.23** is affected.

Q: What can hackers do? (Privileges/Data)

🔓 **Privileges**: Attacker gains **High** impact on Confidentiality, Integrity, and Availability. 🌐 **Data**: Can likely execute arbitrary code, control the router, and access internal network data.

Q: Is exploitation threshold high? (Auth/Config)

⚡ **Threshold**: **LOW**. 🚫 **Auth**: No authentication required (PR:N). 🌍 **Access**: Network accessible (AV:N). 🎯 **Complexity**: Low (AC:L). Easy to exploit remotely.

Q: Is there a public Exp? (PoC/Wild Exploitation)

📂 **Public Exp**: Yes. 🔗 **Source**: GitHub PoC available (M4st3rYi/IoTVulPocs). 📝 **Details**: VDB-323866 provides technical descriptions and indicators.

Q: How to self-check? (Features/Scanning)

🔍 **Check**: Scan for HTTP requests to `/goform/AdvSetMacMtuWa`. 📡 **Feature**: Look for the `wanMTU` parameter in POST requests. 🛡️ **Tool**: Use vulnerability scanners checking for CWE-121 in Tenda firmware.

Q: Is it fixed officially? (Patch/Mitigation)

🛡️ **Fix**: Check Tenda official website for firmware updates. 🔄 **Mitigation**: Update to a patched version if available. 📞 **Contact**: Refer to Tenda support for security advisories.

Q: What if no patch? (Workaround)

🚧 **Workaround**: Block external access to the router's management interface. 🚫 **Filter**: Disable WAN access to `/goform/` endpoints if possible. 📵 **Isolate**: Segment IoT devices from critical network assets.

Q: Is it urgent? (Priority Suggestion)

🔥 **Priority**: **CRITICAL**. 🚨 **Urgency**: High. CVSS Score indicates severe impact. Immediate patching or mitigation is strongly recommended due to low exploitation barrier.
