CVE-2024-4547

9.8 CRITICAL

📋 TL;DR

An unauthenticated SQL injection vulnerability in Delta Electronics DIAEnergie allows remote attackers to execute arbitrary SQL commands via specially crafted 'RecalculateScript' messages. This affects DIAEnergie v1.10.1.8610 and prior versions, potentially compromising the entire database and system.

💻 Affected Systems

Products:
  • Delta Electronics DIAEnergie
Versions: v1.10.1.8610 and prior
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: CEBC.exe component processes messages on default ports; unauthenticated access makes this particularly dangerous.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise including data theft, data manipulation, remote code execution via database functions, and full control over the DIAEnergie application.

🟠

Likely Case

Database compromise leading to sensitive industrial data exposure, configuration manipulation, and potential disruption of energy management operations.

🟢

If Mitigated

Limited impact if proper network segmentation, database permissions, and input validation are in place, though SQL injection could still expose some data.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

SQL injection via fourth field of 'RecalculateScript' message using '~' separator; simple to exploit once message format is understood.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v1.10.1.8611 or later

Vendor Advisory: https://www.deltaww.com/en-US/Support/Security-Advisory/Detail/Delta-Electronics-DIAEnergie-SQL-Injection-Vulnerability-CVE-2024-4547

Restart Required: Yes

Instructions:

1. Download latest DIAEnergie version from Delta Electronics support portal. 2. Backup current installation and database. 3. Run installer to upgrade to v1.10.1.8611 or later. 4. Restart all DIAEnergie services and verify functionality.

🔧 Temporary Workarounds

Network Segmentation

windows

Isolate DIAEnergie systems from untrusted networks using firewalls.

Windows Firewall: New-NetFirewallRule -DisplayName 'Block DIAEnergie Ports' -Direction Inbound -Protocol TCP -LocalPort 1433,502 -Action Block

Input Validation Filter

all

Implement WAF or proxy to filter SQL injection patterns in 'RecalculateScript' messages.

🧯 If You Can't Patch

  • Implement strict network access controls to limit connections to DIAEnergie systems only from trusted sources.
  • Monitor and alert on unusual database queries or CEBC.exe process behavior.

🔍 How to Verify

Check if Vulnerable:

Check DIAEnergie version in Help > About; if version is 1.10.1.8610 or lower, system is vulnerable.

Check Version:

Check DIAEnergie GUI Help > About or examine installed program version in Windows Programs and Features.

Verify Fix Applied:

Verify version is 1.10.1.8611 or higher and test that 'RecalculateScript' messages with SQL injection payloads are rejected.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • CEBC.exe processing messages with '~' separators containing SQL keywords
  • Failed login attempts following SQL injection patterns

Network Indicators:

  • TCP connections to DIAEnergie ports (typically 1433 for SQL Server, 502 for Modbus) with payloads containing SQL injection patterns
  • Unusual traffic patterns to CEBC.exe service

SIEM Query:

source="*DIAEnergie*" AND ("RecalculateScript" OR "~" AND (SELECT OR UNION OR INSERT OR DELETE))
