VULNERABILITY DETAILS

Successful exploitation of this vulnerability could potentially allow an authorized, but non-privileged, local user to execute arbitrary code with elevated privileges on the system. A well-defined service path enables Windows to easily find the path to a service; this is accomplished by containing the path within quotation marks. Without quotation marks, any whitespace in the file path remains ambiguous, and an attacker could drop a malicious executable if the service path is discovered.
This vulnerability allows an authorized individual with access to a file system to possibly escalate privileges by inserting arbitrary code into the unquoted service path. When the Windows Service Manager starts the service, it will attempt to launch the implanted executable rather than the intended and authentic executable.
A CVSS v3 base score of 8.8 has been assigned; the CVSS v3 vector string is: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

RISK MITIGATIONS

Where feasible, precautions and risk mitigation strategies to this type of attack, like those listed below, are recommended. When possible, multiple strategies should be employed simultaneously.
Rockwell Automation recommends upgrading to the latest version of FactoryTalk Activation. To download v4.01 or later, go to this link for the Product Compatibility and Download Center (PCDC) and select “Select Files” icon for all Free Downloads. Select latest FactoryTalk Activation from the list of downloads.

Update: August 24, 2017
Customers can consult with the Product Compatibility and Download Center Standard Views –> Software Latest Versions –> FactoryTalk Activation for compatibility details concerning the latest FactoryTalk Activation Manager.

Note: When centralizing FactoryTalk Activation Manager (FTAM) to a single server host, it is important to ensure that the centralized Activation server is running a version of FactoryTalk Activation Manager equal to, or greater than, the latest version of client FTAM on your network. It is important to update the central activation servers before client activation servers. For details visit Knowledgebase Article ID 612825 Managing Remote FactoryTalk Activation Manager Servers.

If unable to upgrade to the latest version visit KnowledgeBase Article ID 939382, which describes how to identify whether or not your service path contains spaces (i.e. is vulnerable); how to manually address this vulnerability through a registry edit; and walks through the process of doing such edits.

Where feasible, precautions and risk mitigation strategies to this type of attack, like those listed below, are recommended. When possible, multiple strategies should be employed simultaneously.

• Follow industry best-practices to harden your PCs and Servers, including anti-virus/anti-malware and application whitelisting solutions. These recommendations are published in Knowledgebase Article ID 546987.
• Use trusted software, software patches, anti-virus / anti-malware programs, and interact only with trusted web sites and attachments.
• Employ training and awareness programs to educate users on the warning signs of a phishing or social engineering attack.
• Help minimize network exposure for all control system devices and/or systems, and confirm that 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. Also recognize that a VPN is only as secure as the connected devices.
• Ensure that the least-privilege user principle is followed, and user/service account access to shared resources (such as a database) is only granted with a minimum amount of rights as needed.
