Horizon Alert
Summary of the vulnerability and why it matters
The identified Rockwell Automation products contain a flaw related to how account passwords are protected. The cryptographic key used for password protection is embedded directly within the software. This embedded key could be discovered by an attacker, potentially enabling them to conduct further attacks and gain unauthorized remote access to the controller. This could lead to a compromise of critical operational systems.
- Rockwell Automation MicroLogix controllers and RSLogix 500 software
- Embedded cryptographic key can be discovered
- Unauthorized remote access to controllers
Attack Path
How an attacker could exploit the issue
The cryptographic key used to protect account passwords is hardcoded within the RSLogix 500 software. An attacker could discover these keys and exploit them to perform further cryptographic attacks. This could allow a remote attacker to gain unauthorized access to the controller.
- The cryptographic key is exposed.
- An attacker identifies the key.
- Unauthorized access to the controller results.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability affects specific Rockwell Automation industrial control systems and software. Attackers with advanced skills could exploit a weakness in how account passwords are protected. This could potentially allow unauthorized remote access to control system functions, posing a significant risk to operational integrity.
- Likely attacker skill level: Advanced.
- Required access or conditions: Network access.
- Business risk or urgency: Significant operational risk.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability impacts Rockwell Automation MicroLogix controllers and RSLogix 500 software. Attackers can exploit a hardcoded cryptographic key to gain unauthorized access to controllers, potentially leading to system compromise.
