CVE-2025-15045 — AI Deep Analysis Summary

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

🚨 **Essence**: CVE-2025-15045 is a **Stack-based Buffer Overflow** in Tenda WH450. 💥 **Consequences**: Attackers can crash the system or execute arbitrary code, leading to total device compromise.

Q: Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: **CWE-121** (Stack-based Buffer Overflow). The flaw lies in the **HTTP Request Handler** processing the `/goform/Natlimit` parameter `page`. Improper bounds checking allows stack corruption.

Q: Who is affected? (Versions/Components)

📦 **Affected**: **Tenda WH450** (Wireless Access Point). Specifically **Version 1.0.0.18**. 🇨🇳 Vendor: Tenda (China).

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

🔓 **Impact**: **Critical** (CVSS 9.8). Hackers gain **High** Confidentiality, Integrity, and Availability impact. Potential for **Remote Code Execution (RCE)** with no authentication required.

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

⚡ **Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. Network-accessible, Low complexity, **No Privileges** needed, No User Interaction required. Easy to exploit!

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

💣 **Exploit Status**: **YES**. Public PoCs exist on GitHub (`z472421519/BinaryAudit`). 📂 See `Natlimit/Natlimit.md` for reproduction steps. Wild exploitation is possible.

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

🔍 **Self-Check**: Scan for Tenda WH450 devices running **v1.0.0.18**. Test the `/goform/Natlimit` endpoint with oversized `page` parameters to trigger buffer overflow. 🕵️♂️

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

🩹 **Patch**: Official patch info not explicitly detailed in the snippet, but the vendor is **Tenda**. Check `https://www.tenda.com.cn/` for firmware updates. ⏳

Q: What if no patch? (Workaround)

🚧 **Workaround**: If no patch, **disable remote management**. Restrict access to the admin interface via **Firewall rules**. Monitor logs for abnormal `/goform/Natlimit` requests. 🛑

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL**. High CVSS score + Public PoC + No Auth needed. **Patch immediately** or isolate the device. Do not ignore! ⏱️
