Security readout for executives and security teams
Plain-English summary
This flaw can let an unauthenticated remote user put certain Rockwell Automation 5370/5570 controllers into a major non-recoverable fault by loading an invalid project. For operations, that means possible controller outage and process disruption, not evidence of data theft.
Executive priority
Treat as urgent for environments using these controllers in production, because successful exploitation can stop control equipment and disrupt operations. Prioritize plants where controller programming interfaces are reachable beyond tightly controlled engineering networks.
Technical view
CVE-2025-12011 is a CWE-120 buffer overflow denial-of-service vulnerability in CompactLogix 5370, Compact GuardLogix 5370, ControlLogix 5570, and GuardLogix 5570 controllers version 35.015 and earlier. CVSS 4.0 is 9.2 with network attack vector, low complexity, no privileges, and high availability impact.
Likely exposure
Exposure is likely where affected Rockwell Automation 5370 or 5570 controllers run version 35.015 or earlier and can receive remote project loads from reachable networks.
Exploitation context
The provided sources do not establish active exploitation, and CISA KEV status is false. The described outcome is operational denial of service through an invalid project causing major non-recoverable fault.
Researcher notes
Evidence is limited to the CVE record details and Rockwell advisory reference. The source bundle names affected families, versions, CWE-120, CVSS 9.2, and DoS/MNRF impact, but does not provide exploit evidence or detailed patch instructions.
Mitigation direction
- Review Rockwell Automation advisory SD1781 for vendor remediation guidance.
- Inventory affected controller models and firmware versions across OT sites.
- Reduce network reachability to affected controllers until vendor guidance is applied.
- Restrict project-loading capability to authorized engineering systems and users.
Validation and detection
- Confirm whether deployed controllers match the listed 5370 or 5570 product families.
- Check firmware or controller version against 35.015 and earlier.
- Review OT network paths that could allow remote project loading.
- Document compensating controls and remediation status per site.
