Horizon Alert
Summary of the vulnerability and why it matters
The identified flaw impacts industrial control systems that use Omron CX-One CX-Programmer software and CJ2M or CJ2H PLC devices. The affected components transmit passwords in cleartext, making them susceptible to unauthorized access and potential manipulation. This could disrupt industrial operations and expose sensitive control system data.
- Vulnerable Omron industrial software and devices
- Cleartext password transmission flaw
- Unauthorized access to sensitive data
Attack Path
How an attacker could exploit the issue
Attackers can exploit vulnerabilities in Omron CX-One software and certain PLC devices by transmitting passwords in cleartext over the network. This allows unauthorized individuals to gain sensitive information during unlock requests. The exploitation of this vulnerability could lead to unauthorized access and control over industrial systems.
- Network exposure required.
- Attackers sniff network traffic.
- Trigger unlock, obtain credentials.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability allows remote attackers to obtain sensitive information by transmitting passwords in cleartext over the network during an unlock request. Exploitation could expose credentials, potentially leading to unauthorized system access. The business risk is associated with unauthorized access and potential disruption of operational technology systems.
- Attacker skill level: Low
- Required access or conditions: Network access
- Business risk or urgency: High
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability relates to password transmission methods in specific Omron products, potentially allowing unauthorized access to sensitive information. The primary risk stems from network sniffing during unlock requests, which could expose credentials. This could impact operational technology systems by enabling unauthorized control or access.
- Identify affected Omron CX-Programmer, CJ2M, and CJ2H PLC devices.
- Reduce exposure by isolating affected systems.
- Apply vendor fixes, verify implementation, and monitor network traffic.
