CVE-2023-28654
📋 TL;DR
Osprey Pump Controller version 1.01 contains a hidden administrative account with a hardcoded password that cannot be changed, allowing full access to the web management interface. This affects all users of this specific version of the industrial control system. Attackers can exploit this to gain complete control over pump operations.
💻 Affected Systems
- Osprey Pump Controller
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete takeover of pump controller allowing manipulation of industrial processes, potential physical damage to equipment, environmental contamination, or disruption of critical water/wastewater systems.
Likely Case
Unauthorized access to configuration settings leading to operational disruption, data theft, or malicious reconfiguration of pump parameters.
If Mitigated
Limited impact if device is isolated behind multiple network security layers with strict access controls and monitoring.
🎯 Exploit Status
Exploitation requires only knowledge of the hardcoded credentials and network access to the device. No special tools or skills needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-23-082-06
Restart Required: No
Instructions:
No official patch available. Contact vendor for updated firmware or replacement options. Follow CISA advisory recommendations.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Osprey Pump Controller on separate VLAN with strict firewall rules allowing only necessary traffic from authorized management systems.
Access Control Lists
allImplement network ACLs to restrict access to the controller's management interface to specific IP addresses only.
🧯 If You Can't Patch
- Deploy network monitoring and intrusion detection specifically for traffic to/from the pump controller
- Implement physical security controls and ensure only authorized personnel have physical access to the device
🔍 How to Verify
Check if Vulnerable:
Check device version via web interface or serial console. If version is 1.01, device is vulnerable.Check Version:
Check web interface login page or device configuration menu for version informationVerify Fix Applied:
No fix available to verify. Monitor for vendor firmware updates and verify version after update.📡 Detection & Monitoring
Log Indicators:
- Failed login attempts followed by successful login with unknown account
- Configuration changes from unexpected source IPs
- Access to administrative functions from non-standard accounts
Network Indicators:
- HTTP/HTTPS traffic to pump controller from unexpected IP ranges
- Multiple authentication attempts to web interface
- Unusual configuration change requests
SIEM Query:
source_ip=* AND dest_ip=[pump_controller_ip] AND (http_method=POST OR http_uri CONTAINS "/config" OR http_status=200 AFTER http_status=401)
