CVE-2026-6560 — AI Deep Analysis Summary

Q: Root Cause? (CWE/Flaw)

🔍 **Root Cause**: - **CWE-120**: Classic **stack buffer overflow**. - Flaw point: The `Edit_BasicSSID` function processes parameter `param` without length validation 🧨 → overflow write.

Q: Who is affected? (Versions/Components)

🎯 **Impact Scope**: - **Device Model**: H3C Magic B0 - **Version**: ≤ 100R002 - **Component**: Web interface `/goform/aspForm`

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

👾 **Attacker Capabilities**: - **Privilege**: Can obtain **high privilege** (CVSS:C=H/I=H/A=H) - **Data**: Can read/tamper with/delete critical data 🗃️ - **Control**: Can remotely execute malicious commands 💻

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

⚠️ **Existing Exploit**: - 📌 POC: Publicly disclosed 🧨 (exploit available on GitHub) - 📌 Exploit status: **Exploitable + high in-the-wild risk** 🚨

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

🔎 **Self-Check Method**: - ✅ Check device model & firmware ≤ 100R002 📋 - ✅ Search for access to `/goform/aspForm?Edit_BasicSSID` 🕵️ - ✅ Use VDB-358197 signature detection 🛡️ (CTI Indicators)

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

❌ **Official Fix**: None yet! - 📅 Vendor contacted → **no response** 🤐 - 🚫 No patch | no mitigation measures released

Q: What if no patch? (Workaround)

🛑 **Temporary Mitigation**: - 🔒 Restrict web management access (IP whitelist / VPN) 🌐 - 🚷 Disable or remove `Edit_BasicSSID` feature (if supported) - 📉 Minimize use of low-privilege accounts for login ⬇️

Q: Is it urgent? (Priority Suggestion)

🔥 **Priority**: Extremely high! - CVSS 9.1 🚨 | remote + high severity + exploit exists - 💡 Recommendation: **Immediately investigate & isolate affected devices** 🏃
