CVE-2022-1375
📋 TL;DR
Delta Electronics DIAEnergie versions prior to 1.8.02.004 contain a blind SQL injection vulnerability in the DIAE_slogHandler.ashx endpoint. This allows attackers to execute arbitrary SQL queries, potentially leading to data theft, system compromise, and remote code execution. Organizations using DIAEnergie for industrial energy management are affected.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise: attacker gains administrative access, exfiltrates sensitive industrial data, executes arbitrary system commands, and potentially disrupts industrial operations.
Likely Case
Database compromise: attacker extracts credentials, configuration data, and operational information, then pivots to other systems in the network.
If Mitigated
Limited impact: proper network segmentation and input validation prevent successful exploitation, limiting damage to isolated systems.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited with readily available tools. The blind nature requires more effort but is still highly exploitable.
