CVE-2025-26390 — AI Deep Analysis Summary

🚨 **Essence**: SQL Injection in Siemens OZW672/OZW772. 💥 **Consequences**: Attackers can bypass authentication checks. This leads to potential full system compromise, data theft, or service disruption.

🛡️ **CWE-89**: Improper Neutralization of Special Elements used in an SQL Command. 🐛 **Flaw**: The authentication data checking mechanism fails to sanitize inputs, allowing malicious SQL code to execute.

🏢 **Vendor**: Siemens. 📦 **Products**: OZW672 (Building Controller) & OZW772 (Web Server for Synco/Synco living). ⚠️ **Affected Versions**: Specifically **V6.0**.

🕵️ **Privileges**: Bypasses authentication entirely! 📂 **Data**: High impact on Confidentiality, Integrity, and Availability (CVSS H:H:H). Attackers gain unauthorized access to sensitive building control data.

⚡ **Threshold**: LOW. 🌐 **Network**: Attack Vector is Network (AV:N). 🔑 **Auth**: Privileges Required are None (PR:N). No user interaction needed (UI:N). Easy to exploit remotely.

📜 **Public Exploit**: The provided data shows **empty PoCs** (pocs: []). However, given the CVSS score and nature, wild exploitation is likely imminent. Monitor for community releases.

🔍 **Self-Check**: Scan for Siemens OZW672/OZW772 devices running **V6.0**. Look for SQL injection points in authentication endpoints. Use standard SQLi scanners against the Web Server interface.

🔧 **Official Fix**: Yes. Siemens has released a security advisory (SSA-047424). 📥 **Action**: Check the Siemens Cert Portal for patches or updates to upgrade from V6.0.

🚧 **Workaround**: If patching is delayed, restrict network access to these devices. Implement WAF rules to block SQL injection patterns. Disable unnecessary web services if possible.

🔥 **Urgency**: CRITICAL. 📅 **Published**: May 13, 2025. With CVSS 9.0+ and no auth required, prioritize immediate patching or mitigation to prevent unauthorized building control access.
