CVE-2023-0822

8.8 HIGH

📋 TL;DR

DIAEnergie versions before v1.9.03.001 contain an improper authorization vulnerability that allows unauthorized users to bypass authentication and access privileged functionality. This affects industrial control systems using DIAEnergie for energy management. Attackers could manipulate system operations without proper credentials.

💻 Affected Systems

Products:
  • DIAEnergie
Versions: All versions prior to v1.9.03.001
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Industrial control system software typically deployed in energy management environments.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Unauthorized attackers gain administrative access to industrial energy management systems, potentially disrupting critical infrastructure operations, manipulating energy data, or causing physical damage through unauthorized control.

🟠

Likely Case

Attackers access sensitive energy management data, modify system configurations, or disrupt normal operations by bypassing authentication mechanisms.

🟢

If Mitigated

With proper network segmentation and access controls, impact is limited to isolated systems with minimal operational disruption.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

CWE-285 indicates improper authorization, suggesting relatively straightforward exploitation once the vulnerability is understood.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v1.9.03.001

Vendor Advisory: https://www.cisa.gov/uscert/ics/advisories/icsa-22-298-06

Restart Required: Yes

Instructions:

1. Download DIAEnergie v1.9.03.001 or later from official vendor sources. 2. Backup current configuration and data. 3. Install the updated version following vendor documentation. 4. Restart the application and verify functionality.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate DIAEnergie systems from untrusted networks and implement strict firewall rules.

Access Control Lists

all

Implement strict network access controls to limit connections to DIAEnergie systems.

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate vulnerable systems from untrusted networks
  • Deploy additional authentication layers and monitor for unauthorized access attempts

🔍 How to Verify

Check if Vulnerable:

Check DIAEnergie version in application interface or configuration files. Versions below v1.9.03.001 are vulnerable.

Check Version:

Check application interface or consult vendor documentation for version verification method

Verify Fix Applied:

Confirm version is v1.9.03.001 or later and test authentication mechanisms for proper authorization enforcement.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized access attempts
  • Authentication bypass patterns
  • Privileged operations from unauthenticated users

Network Indicators:

  • Unexpected connections to DIAEnergie ports
  • Traffic patterns indicating authentication bypass

SIEM Query:

source="DIAEnergie" AND (event_type="authentication_failure" OR event_type="privileged_access")
