View CSAF

1. EXECUTIVE SUMMARY

• CVSS v4 8.7
• ATTENTION: Exploitable remotely/low attack complexity
• Vendor: Rockwell Automation
• Equipment: ThinManager
• Vulnerabilities: Improper Restriction of Operations within the Bounds of a Memory Buffer, Incorrect Default Permissions

2. RISK EVALUATION

Successful exploitation of these vulnerabilities could allow an attacker to escalate privileges and cause a denial-of-service condition.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of ThinManager, a software management platform, are affected:

• ThinManager: Version 14.0.0 and prior

3.2 VULNERABILITY OVERVIEW

3.2.1 IMPROPER RESTRICTION OF OPERATIONS WITHIN THE BOUNDS OF A MEMORY BUFFER CWE-119

A denial-of-service vulnerability exists in Rockwell Automation ThinManager. The software fails to adequately verify the outcome of memory allocation while processing Type 18 messages. If exploited, a threat actor could cause a denial of service on the target software.

CVE-2025-3618 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (CVSS:3.1/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-2025-3618. A base score of 8.7 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N).

3.2.2 INCORRECT DEFAULT PERMISSIONS CWE-276

A privilege escalation vulnerability exists in Rockwell Automation ThinManager. When the software starts up, files are deleted in the temporary folder causing the Access Control Entry of the directory to inherit permissions from the parent directory. If exploited, a threat actor could inherit elevated privileges.

CVE-2025-3617 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2025-3617. A base score of 8.5 has been calculated; the CVSS vector string is (CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.3 BACKGROUND

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

3.4 RESEARCHER

An anonymous researcher working with Trend Micro’s Zero Day Initiative reported these vulnerabilities to CISA.

4. MITIGATIONS

Rockwell Automation encourages users to update ThinManager to v14.0.2 or later to mitigate CVE-2025-3617.

Rockwell Automation fixed CVE-2025-3618 in the following versions of ThinManager:

• ThinManager v11.2.11
• ThinManager v12.0.9
• ThinManager v13.1.5
• ThinManager v13.2.4
• ThinManager v14.0.2
• For information on how to mitigate security risks on industrial automation control systems, Rockwell Automation encourages users to implement their suggested security best practices to minimize the risk of the vulnerability.

For more information about these issues, please see the Rockwell Automation security advisory SD1727.

Stakeholder-Specific Vulnerability Categorization can be used to generate more environment-specific prioritization.

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.
