📋 TL;DR
This SQL injection vulnerability in Riello Netman 204 allows attackers to execute arbitrary SQL commands on the SQLite measurement database. It affects all versions through 4.05, potentially enabling data theft, manipulation, or denial of service. Only systems using the measurement data component are vulnerable.
💻 Affected Systems
- Riello Netman 204
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of measurement database including data deletion, manipulation, or potential privilege escalation to underlying system via SQLite functions.
Likely Case
Unauthorized access to measurement data, data modification, or denial of service affecting monitoring capabilities.
If Mitigated
Limited to measurement data only, no access to configuration or control systems if properly segmented.
🎯 Exploit Status
SQL injection vulnerabilities typically have low exploitation complexity once the vulnerable endpoint is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.06 or later
