4.2 VULNERABILITY OVERVIEW

4.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE SCRIPTING') CWE-79

A Cross-Site Scripting (“XSS”) vulnerability was found in certain versions of Wibu-Systems CodeMeter that may allow local attackers to inject arbitrary web script or HTML via a specific field in a configuration file, allowing an attacker to access sensitive information, or even rewrite the content of the HTML page.

CVE-2017-13754 has been assigned to this vulnerability. A CVSS v3 base score of 2.7 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:N/UI:R/S:C/C:N/I:L/A:N).

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

A custom string copying function of the license server manager in FlexNet Publisher does not use proper bounds checking on incoming data, allowing a remote, unauthenticated user to send crafted messages with the intent of causing a buffer overflow.

CVE-2015-8277 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

4.3 BACKGROUND

• Critical Infrastructure Sectors: Chemical, Critical Manufacturing, Food and Agriculture, Water and Wastewater Systems
• Countries/Areas Deployed: Worldwide
• Company Headquarters Location: U.S.

4.4 RESEARCHER

Rockwell Automation reported these vulnerabilities to NCCIC.

5. MITIGATIONS

Rockwell Automation recommends users with affected versions of CodeMeter and/or FlexNet Publisher that were installed with FactoryTalk Activation Manager to update Factory Talk Activation Manager to v4.02. If unable to update FactoryTalk Activation Manager to v4.02, update CodeMeter to a compatible version of CodeMeter that is compatible with FactoryTalk Activation Manager.

Rockwell Automation also encourages users to combine the updates above with these general security guidelines to employ multiple strategies simultaneously.

• Block all traffic to EtherNet/IP or other CIP protocol-based devices from outside the Manufacturing Zone by blocking or restricting access to Port 2222/TCP and UDP and Port 44818/TCP and UDP, using proper network infrastructure controls, such as firewalls, UTM devices, or other security appliances. For more information on TCP/UDP ports used by Rockwell Automation Products, see Knowledgebase Article ID 898270 available at: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/898270/page/1 (Login required).
• Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
• Locate control system networks and devices behind firewalls and isolate them from the business network.
• When remote access is required, use secure methods such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. VPN is only as secure as the connected devices.
