CVE-2022-26349
📋 TL;DR
Delta Electronics DIAEnergie versions prior to 1.8.02.004 contain a blind SQL injection vulnerability in the DIAE_eccoefficientHandler.ashx endpoint. This allows attackers to execute arbitrary SQL queries, potentially leading to data theft, system compromise, and command execution. Organizations using affected DIAEnergie installations for industrial energy management are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to execute arbitrary system commands, exfiltrate sensitive industrial data, modify critical configurations, and pivot to other industrial control systems.
Likely Case
Database compromise leading to theft of operational data, manipulation of energy management parameters, and potential disruption of monitoring systems.
If Mitigated
Limited impact with proper network segmentation and input validation, potentially only allowing information disclosure about database structure.
🎯 Exploit Status
SQL injection vulnerabilities are well-understood and frequently weaponized. The blind nature adds some complexity but doesn't prevent exploitation.
