CVE-2026-27755 — AI Deep Analysis Summary

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

🚨 **Essence**: Weak session ID generation in SODOLA SL902-SWTGW124AS. 💥 **Consequences**: Attackers can predict MD5-based cookies to bypass authentication. Full system compromise possible.

Q: Root Cause? (CWE/Flaw)

🛡️ **CWE-330**: Use of Insufficiently Random Values. 🔍 **Flaw**: The device uses a weak, predictable MD5 mechanism for session identifiers instead of cryptographically secure random generation.

Q: Who is affected? (Versions/Components)

🏭 **Vendor**: SODOLA Networks (Shenzhen Hongyavision Tech). 📦 **Product**: SODOLA SL902-SWTGW124AS (Industrial Switch). ⚠️ **Affected**: Versions **200.1.20 and earlier**.

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

🕵️ **Hackers Can**: 1. **Bypass Auth**: Guess session cookies. 2. **Gain Access**: Login as admin/users without credentials. 3. **Full Control**: Read/Modify config, disrupt network (CVSS High Impact).

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

📉 **Threshold: LOW**. 🔓 **Auth**: None required (PR:N). 🌐 **Network**: Remote (AV:N). 🖱️ **UI**: None required (UI:N). ⚡ **Complexity**: Low (AC:L). Easy to exploit remotely.

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

🛠️ **Fix**: Update firmware to **version 200.1.21 or later**. 📥 **Source**: Official SODOLA website or vendor support portal. ✅ **Status**: Patch available for the specific vulnerability.

Q: Is it urgent? (Priority Suggestion)

🔥 **Priority: CRITICAL**. 📊 **CVSS**: 9.8 (High). ⏱️ **Urgency**: Patch immediately. Remote, unauthenticated exploitation makes this a high-risk target for industrial networks. Do not delay.
