CVE-2025-2287 Overview
CVE-2025-2287 is a local code execution vulnerability in Rockwell Automation Arena simulation software. The flaw originates from an uninitialized pointer caused by improper validation of user-supplied data within DOE file processing. An attacker who convinces a legitimate user to open a crafted .doe file can disclose process memory and execute arbitrary code in the context of the Arena application. The issue is tracked under CWE-457 (Use of Uninitialized Variable) and CWE-824 (Access of Uninitialized Pointer).
Critical Impact
Successful exploitation grants arbitrary code execution and information disclosure on engineering workstations running Arena, exposing OT design environments to compromise.
Affected Products
- Rockwell Automation Arena (see vendor advisory for affected build ranges)
- Engineering workstations processing untrusted .doe simulation files
- Industrial environments where Arena is used to model OT processes

Technical Details for CVE-2025-2287
Vulnerability Analysis
The vulnerability resides in Arena's parser for the proprietary DOE document format. When Arena loads a malicious .doe file, the parser fails to validate user-supplied fields before referencing a pointer that has not been initialized. The resulting read or write occurs against an attacker-influenced memory address.
Because the uninitialized pointer can hold residual stack or heap contents, an attacker who shapes the file structure can steer the dereference toward controlled data. This converts a memory safety defect into a primitive suitable for both information disclosure and arbitrary code execution. The defect requires user interaction, so attackers typically pair it with social engineering targeting engineers and integrators.
Root Cause
The root cause is improper input validation during deserialization of the DOE file structure. Arena does not confirm that required fields populate the pointer before use, mapping to [CWE-457] and [CWE-824]. Residual memory values are trusted as valid object references, allowing the parser to dereference attacker-influenced addresses.
Attack Vector
Exploitation is local and requires a legitimate user to open the malicious file. Delivery typically occurs through phishing email attachments, shared project repositories, or removable media in OT environments. Once the file is opened, exploitation proceeds without further interaction and runs with the privileges of the Arena user.
No public proof-of-concept is available, and CISA KEV does not list this CVE as known-exploited. Technical specifics are documented in the Rockwell Automation Security Advisory SD1726.
Detection Methods for CVE-2025-2287
Indicators of Compromise
- Unexpected .doe files arriving via email, chat, or shared drives, particularly from external senders
- Arena processes spawning child processes such as cmd.exe, powershell.exe, or rundll32.exe
- Crash dumps or Windows Error Reporting entries referencing Arena modules following a file open
- Outbound network connections initiated by the Arena process to non-Rockwell infrastructure
Detection Strategies
- Hunt for process lineage where Arena is the parent of scripting or LOLBin executables
- Alert on Arena writing executables, scheduled tasks, or registry Run keys
- Inspect email and file-share gateways for .doe attachments and quarantine for review
- Correlate Arena application crashes with subsequent suspicious child-process activity
Monitoring Recommendations
- Ingest endpoint process and file telemetry from engineering workstations into a centralized data lake for correlation
- Track first-seen .doe file hashes across the environment and flag rapid distribution
- Enable behavioral identification on engineering hosts to catch post-exploitation activity such as credential access or lateral movement
- Review Windows Defender or EDR exclusions on OT workstations that may shield the Arena process directory
How to Mitigate CVE-2025-2287
Immediate Actions Required
- Apply the fixed Arena release referenced in Rockwell Automation advisory SD1726 on all engineering workstations
- Block .doe attachments at the email gateway from untrusted external senders
- Instruct Arena users to open simulation files only from verified, internal sources
- Inventory hosts running Arena and prioritize patching for internet-connected or dual-homed workstations
Patch Information
Rockwell Automation has released a fixed version of Arena addressing CVE-2025-2287. Refer to advisory SD1726 for the exact patched build numbers, download locations, and upgrade guidance. Customers without active support contracts should contact Rockwell Automation TechConnect to obtain the update.
Workarounds
- Restrict Arena execution to standard user accounts to limit the impact of code execution
- Use application allowlisting to prevent Arena from launching scripting interpreters or unsigned binaries
- Store project files on access-controlled shares and require integrity verification before opening
- Segment engineering workstations from general corporate networks per ISA/IEC 62443 zone and conduit guidance
