Successful exploitation of these vulnerabilities may allow an attacker to bypass authentication in the communications connection process to login and operate the controller products without authorization.
The following versions of NJ/NX-series, a machine automation controller, are affected:
Use of hard-coded credentials vulnerability exists in machine automation controller NJ series models v1.48 and earlier, machine automation controller NX7 series models v1.28 and earlier, machine automation controller NX1 series models v1.48 and earlier, automation software Sysmac Studio models v1.49 and earlier, and programmable terminal (PT) NA series NA5-15W/NA5-12W/NA5-9W/NA5-7W models with runtime v1.15 and earlier; this may allow a remote attacker who successfully obtained the user credentials by analyzing the affected product to access the controller.
CVE-2022-34151 has been assigned to this vulnerability. A CVSS v3 base score of 9.4 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H).
An attacker who can capture and analyze communication between the affected controllers and either automation software Sysmac Studio and/or a programmable terminal (PT) can obtain sensitive information that would allow the attacker to bypass authentication and access the controller.
CVE-2022-33208 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H).
Reid Wightman of Dragos reported these vulnerabilities to CISA.
Omron recommends the following:
For information on how to obtain and update firmware for the countermeasure version of the product, contact Omron sales office or distributors. Users can update the Sysmac Studio to the latest versions using the installed Omron Automation Software AutoUpdate tool.
Omron recommends customers take the following mitigation measures to minimize the risk of exploitation of this vulnerability:
Enable antivirus protection
Implement security measures to prevent unauthorized access:
Protect data input and output:
Use data recovery:
For more information see Omronβs advisory: OMSR-2022-001
This vulnerability and countermeasures correspond to the those reported in the CISA ICS Alert: APT Cyber Tools Targeting ICS/SCADA Devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01BβTargeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
