CVSS v4 8.7
ATTENTION: Exploitable remotely/low attack complexity
Vendor: Rockwell Automation
Equipment: SequenceManager
Vulnerabilities: Unquoted Search Path or Element

2. RISK EVALUATION

Successful exploitation of these vulnerabilities could cause a denial-of-service condition.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of SequenceManager, a logix controller-based batch and sequencing solution, are affected:

SequenceManager: Versions prior to 2.0

3.2 Vulnerability Overview

3.2.1 Unquoted Search Path or Element CWE-428

An input validation vulnerability exists in the affected products which could allow a malicious user to send malformed packets to the server and cause a denial-of-service condition. If exploited, the device would become unresponsive, and a manual restart will be required for recovery. Additionally, if exploited, there could be a loss of view for the downstream equipment sequences in the controller. Users would not be able to view the status or command the equipment sequences, however the equipment sequence would continue to execute uninterrupted.

CVE-2024-4609 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-2024-4609. A base score of 8.7 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:H/SC:N/SI:N/SA:N).

3.4 RESEARCHER

Rockwell Automation reported these vulnerabilities to CISA.

4. MITIGATIONS

Rockwell Automation recommends users upgrade to version 2.0 or greater.

There is no fix available for these vulnerabilities in the affected software versions prior to v2.0. Users using the affected software and who are not able to upgrade to one of the corrected versions are encouraged to apply security best practices, where possible.

Security Best Practices

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.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

Do not click web links or open attachments in unsolicited email messages.
Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
