CVE-2024-12175
📋 TL;DR
A use-after-free vulnerability in Rockwell Automation Arena allows arbitrary code execution when a user opens a malicious DOE file. This affects legitimate users of Arena simulation software who could inadvertently execute attacker-crafted files. The vulnerability requires user interaction but grants significant system control.
💻 Affected Systems
- Rockwell Automation Arena
📦 What is this software?
Arena by Rockwellautomation
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control of the affected system, potentially leading to lateral movement, data theft, or disruption of industrial operations.
Likely Case
Local privilege escalation or malware execution on the user's workstation, potentially compromising sensitive simulation data and credentials.
If Mitigated
Limited impact with proper application whitelisting and user training preventing malicious file execution.
🎯 Exploit Status
Requires social engineering to get user to open malicious file; exploitation requires understanding of Arena's file parsing.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 16.20.01
Vendor Advisory: https://www.rockwellautomation.com/en-us/trust-center/security-advisories/advisory.SD1713.html
Restart Required: Yes

🔧 Temporary Workarounds
Restrict DOE file execution
windowsConfigure application control policies to restrict execution of DOE files from untrusted sources.
Using Windows AppLocker or similar: Create rule blocking DOE files from non-approved locations
User awareness training
allTrain users to only open DOE files from trusted sources and verify file integrity.
🧯 If You Can't Patch
- Implement strict application whitelisting to prevent unauthorized code execution
- Isolate Arena workstations from critical networks and implement network segmentation
