CVE-2023-0228

8.8 HIGH

📋 TL;DR

CVE-2023-0228 is an improper authentication vulnerability in ABB Symphony Plus S+ Operations that allows attackers to bypass authentication mechanisms. This affects industrial control systems running affected versions, potentially granting unauthorized access to critical operational interfaces.

💻 Affected Systems

Products:
  • ABB Symphony Plus S+ Operations
Versions: 2.X through 2.1 SP2, 2.2, 3.X through 3.3 SP1, 3.3 SP2
Operating Systems: Windows-based industrial control systems
Default Config Vulnerable: ⚠️ Yes
Notes: Affects industrial control systems used in critical infrastructure sectors.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of industrial control system operations, allowing attackers to manipulate processes, disrupt operations, or cause physical damage to equipment.

🟠

Likely Case

Unauthorized access to operational interfaces leading to data theft, configuration changes, or operational disruption.

🟢

If Mitigated

Limited impact if systems are properly segmented and monitored, with attackers only gaining access to isolated components.

🌐 Internet-Facing: HIGH if systems are exposed to internet, as authentication bypass can be exploited remotely.
🏢 Internal Only: HIGH even internally, as any network access could lead to compromise of critical industrial systems.

🎯 Exploit Status

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

Authentication bypass vulnerabilities typically have low exploitation complexity once discovered.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Versions beyond those listed as affected

Vendor Advisory: https://search.abb.com/library/Download.aspx?DocumentID=7PAA006722&LanguageCode=en&DocumentPartId=&Action=Launch

Restart Required: Yes

Instructions:

1. Contact ABB support for appropriate patches. 2. Apply patches following ABB's industrial control system update procedures. 3. Restart affected systems as required. 4. Verify patch application.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate affected systems from untrusted networks and implement strict access controls.

Access Control Lists

all

Implement strict network ACLs to limit access to only authorized IP addresses.

🧯 If You Can't Patch

  • Implement strict network segmentation and zero-trust architecture
  • Deploy intrusion detection systems and monitor for authentication bypass attempts

🔍 How to Verify

Check if Vulnerable:

Check system version against affected versions list in ABB advisory.

Check Version:

Check via ABB Symphony Plus S+ Operations interface or consult system documentation.

Verify Fix Applied:

Verify system version is updated beyond affected versions and test authentication mechanisms.

📡 Detection & Monitoring

Log Indicators:

  • Failed authentication attempts followed by successful access
  • Unusual access patterns to operational interfaces

Network Indicators:

  • Unauthorized access attempts to S+ Operations ports
  • Traffic patterns indicating authentication bypass

SIEM Query:

source="symphony_plus" AND (event_type="auth_failure" OR event_type="auth_bypass")
