ROCKWELL AUTOMATION FACTORYTALK VIEW ME

Release Date
November 12, 2024
Alert Code
ICSA-24-317-03
Related topics:
Industrial Control System Vulnerabilities, Industrial Control Systems


View CSAF(link is external)


1. EXECUTIVE SUMMARY

 * CVSS v4 7.0
 * ATTENTION: Low attack complexity
 * Vendor: Rockwell Automation
 * Equipment: FactoryTalk View ME
 * Vulnerability: Improper Input Validation


2. RISK EVALUATION

Successful exploitation of this vulnerability could allow a local low-privileged
user to escalate their privileges by changing the macro to execute arbitrary
code.


3. TECHNICAL DETAILS


3.1 AFFECTED PRODUCTS

Rockwell Automation reports that the following versions of FactoryTalk Software
are affected:

 * FactoryTalk View ME, when using default folder privileges: v14.0 and prior


3.2 VULNERABILITY OVERVIEW

3.2.1 IMPROPER INPUT VALIDATION CWE-20(LINK IS EXTERNAL)

A remote code execution vulnerability exists in FactoryTalk View ME. The
vulnerability allows users to save projects within the public directory allowing
anyone with local access to modify and/or delete files. Additionally, a
malicious user could potentially leverage this vulnerability to escalate their
privileges by changing the macro to execute arbitrary code.

CVE-2024-37365(link is external) has been assigned to this vulnerability. A CVSS
v3.1 base score of 7.3 has been calculated; the CVSS vector string is
(CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H(link is external)).

A CVSS v4 score has also been calculated forCVE-2024-37365(link is external). A
base score of 7.0 has been calculated; the CVSS vector string is
(CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N(link is
external)).


3.3 BACKGROUND

 * CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing
 * COUNTRIES/AREAS DEPLOYED: Worldwide
 * COMPANY HEADQUARTERS LOCATION: United States


3.4 RESEARCHER

Rockwell Automation reported this vulnerability to CISA.


4. MITIGATIONS

Rockwell Automation has corrected this problem in V15.0.

Rockwell Automation encourages users of the affected software who are not able
to upgrade to one of the corrected versions to apply the following risk
mitigations where possible.

 * To enhance security and help prevent unauthorized modifications to HMI
   project files, harden the Windows OS by removing the INTERACTIVE group from
   the folder's security properties.
 * Add specific users or user groups and assign their permissions to this folder
   using the least privileges principle. Users with read-only permission can
   still test run and run the FactoryTalk View ME Station.
 * Guidance can be found in FactoryTalk View ME v14 Help topic: "HMI projects
   folder settings". It can be opened through the FactoryTalk View ME Studio
   menu "help\Contents\FactoryTalk View ME Help\Create a Machine Edition
   application->Open applications->HMI project folder settings".
 * Security Best Practices(link is external)

For more information, see Rockwell Automation's security advisory(link is
external)

CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability, 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 this vulnerability has been
reported to CISA at this time.
