CVE-2023-2072
📋 TL;DR
Rockwell Automation PowerMonitor 1000 has stored cross-site scripting vulnerabilities in publicly accessible web pages. Attackers can inject malicious code that executes when authenticated users view those pages, potentially leading to remote code execution. This affects all PowerMonitor 1000 users with vulnerable versions.

📦 What is this software?
Powermonitor 1000 Firmware by Rockwellautomation
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to execute arbitrary code, steal credentials, manipulate device operations, and disrupt industrial processes.
Likely Case
Session hijacking, credential theft, and unauthorized access to device configuration and monitoring data.
If Mitigated
Limited to client-side script execution if proper input validation and output encoding are implemented.
🎯 Exploit Status
Attackers can inject payloads without authentication, but exploitation requires authenticated user interaction. Stored XSS makes exploitation reliable.

🔧 Temporary Workarounds
Network Segmentation
allIsolate PowerMonitor 1000 devices from untrusted networks and limit access to authorized users only.
Web Interface Restriction
allRestrict web interface access to specific IP addresses using firewall rules.
🧯 If You Can't Patch
- Implement strict input validation and output encoding at network perimeter
- Monitor for suspicious web requests and JavaScript payloads in device logs
🔍 How to Verify
Check if Vulnerable:
Check device firmware version via web interface or serial console. Versions below 4.004 are vulnerable.
Check Version:
Check via web interface: Login > System > About, or via serial console using manufacturer-specific commands.
Verify Fix Applied:
Confirm firmware version shows 4.004 or higher in device settings.
