1. EXECUTIVE SUMMARY CVSS v4 7.7 ATTENTION: Exploitable remotely/low attack complexity Vendor: Rockwell Automation Equipment: FactoryTalk Historian SE Vulnerabilities: Missing Release of Resource after Effective Lifetime, Improper Check or Handling of Exceptional Conditions
2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to cause a denial-of-service condition.
3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Rockwell Automation FactoryTalk Historian SE, a data management application, are affected: FactoryTalk Historian SE: Versions v9.0 and prior 3.2 Vulnerability Overview 3.2.1 MISSING RELEASE OF RESOURCE AFTER EFFECTIVE LIFETIME CWE-772 FactoryTalk Historian SE utilizes the AVEVA PI Server, which contains a vulnerability that could allow an unauthenticated user to cause a partial denial-of-service condition in the PI Message Subsystem of a PI Server by consuming available memory. This vulnerability exists in FactoryTalk Historian SE versions 9.0 and earlier. Exploitation of this vulnerability could cause FactoryTalk Historian SE to become unavailable, requiring a power cycle to recover it. CVE-2023-31274 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). A CVSS v4 score has also been calculated for CVE-2023-31274. A base score of 7.7 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:H). 3.2.2 IMPROPER CHECK OR HANDLING OF EXCEPTIONAL CONDITIONS CWE-703 FactoryTalk Historian SE uses the AVEVA PI Server, which contains a vulnerability that could allow an unauthenticated user to remotely crash the PI Message Subsystem of a PI Server, resulting in a denial-of-service condition. This vulnerability exists in FactoryTalk Historian SE versions 9.0 and earlier. Exploitation of this vulnerability could cause FactoryTalk Historian SE to become unavailable, requiring a power cycle to recover it. CVE-2023-34348 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). A CVSS v4 score has also been calculated for CVE-2023-34348. A base score of 7.7 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:H). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: United States 3.4 RESEARCHER Rockwell Automation reported these vulnerabilities to CISA.
4. MITIGATIONS Rockwell Automation has released product updates addressing this vulnerability: FactoryTalk Historian SE: Users using the affected software are encouraged to install FactoryTalk Historian SE version 9.01 or higher as soon as feasible. For more information, see Rockwell Automation’s article.(Login Required) For more information about the AVEVA PI and AVEVA Edge products, see AVEVA-2024-001 and AVEVA-2024-002 CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as: Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected 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 on 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. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted 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. No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
