Horizon Alert
Summary of the vulnerability and why it matters
Rockwell Automation's Studio 5000 Logix Designer and RSLogix 5000 software contain a flaw that allows unauthorized access to Logix controllers. This vulnerability affects a range of Rockwell controllers, including CompactLogix, ControlLogix, DriveLogix, Compact GuardLogix, GuardLogix, and SoftLogix. An attacker could bypass a verification mechanism to authenticate with these controllers. This could lead to unauthorized applications interacting with critical control systems.
- Vulnerable Rockwell design software
- Flaw bypasses controller verification
- Unauthorized controller access and interaction
Attack Path
How an attacker could exploit the issue
Attackers can exploit a vulnerability in Rockwell Automation's Logix controllers, allowing them to bypass security measures. This could enable unauthorized applications to connect with Logix controllers, potentially leading to the manipulation or disruption of industrial processes. The attack requires an attacker to have network access to the affected controller.
- Network access to controller required.
- Attacker bypasses controller verification.
- Unauthorized application connects to controller.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability presents a significant risk to organizations utilizing Rockwell Automation's Logix controllers and associated design software. An unauthenticated attacker with network access could bypass security mechanisms, allowing them to authenticate with and potentially control critical industrial systems. This could lead to disruptions in operational technology (OT) environments, impacting production and potentially causing safety concerns. The widespread use of these products in industrial settings makes this a concerning issue for operational continuity and security.
- Attacker skill: No specific skill level required.
- Access needed: Network access to controllers.
- Business risk: High impact to operations.
Priority actions
Operational Fix
