CVE-2024-12175

7.8 HIGH

📋 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

Products:
  • Rockwell Automation Arena
Versions: All versions prior to 16.20.01
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Requires user to open a malicious DOE file; not exploitable remotely without user interaction.

📦 What is this software?

⚠️ 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.

🌐 Internet-Facing: LOW
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

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

Instructions:

1. Download Arena version 16.20.01 from Rockwell Automation portal. 2. Close all Arena instances. 3. Run the installer with administrative privileges. 4. Follow installation prompts. 5. Restart system after installation completes.

🔧 Temporary Workarounds

Restrict DOE file execution

windows

Configure 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

all

Train 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
