CVE-2024-21764
📋 TL;DR
Rapid SCADA versions before 5.8.4 contain hard-coded credentials that allow attackers to connect to a specific port. This affects all users running vulnerable versions of Rapid SCADA software, potentially exposing industrial control systems to unauthorized access.
💻 Affected Systems
- Rapid SCADA
📦 What is this software?
Rapid Scada by Rapidscada
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to manipulate industrial processes, disrupt operations, or exfiltrate sensitive data from SCADA systems.
Likely Case
Unauthorized access to SCADA systems enabling reconnaissance, data theft, or manipulation of non-critical functions.
If Mitigated
Limited impact if network segmentation isolates SCADA systems and access controls are properly implemented.
🎯 Exploit Status
Hard-coded credentials make exploitation trivial once the specific port is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.8.4
Vendor Advisory: https://rapidscada.org/contact/
Restart Required: Yes
Instructions:
1. Download Rapid SCADA version 5.8.4 or later from official sources. 2. Backup current configuration and data. 3. Install the updated version following vendor instructions. 4. Restart all Rapid SCADA services.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Rapid SCADA systems from untrusted networks using firewalls
Port Restriction
allBlock access to the specific port mentioned in the vulnerability
🧯 If You Can't Patch
- Implement strict network segmentation to isolate SCADA systems
- Monitor network traffic to the affected port for unauthorized access attempts
🔍 How to Verify
Check if Vulnerable:
Check Rapid SCADA version in administration interface or configuration filesCheck Version:
Check ScadaServer.exe or ScadaComm.exe version properties on Windows; check package version on LinuxVerify Fix Applied:
Confirm version is 5.8.4 or higher in administration interface📡 Detection & Monitoring
Log Indicators:
- Unauthorized connection attempts to SCADA port
- Authentication failures from unknown IPs
Network Indicators:
- Unexpected traffic to SCADA port from external sources
- Connection attempts using default credentials
SIEM Query:
source_port: [SCADA_PORT] AND (event_type: authentication_failure OR src_ip NOT IN [allowed_ips])
