High Severity Flaws Patched in Rockwell Automation Tools

High severity vulnerabilities have been patched by Rockwell Automation in the company’s Connected Components Workbench and FactoryTalk Activation tools, ICS-CERT said on Wednesday.

One of the flaws, discovered by researcher Ivan Sanchez and tracked as CVE-2017-5176, affects Connected Components Workbench (CCW), a design and configuration application for Rockwell devices. The product is used worldwide in various industries.

According to ICS-CERT, CCW is affected by a DLL hijacking vulnerability that allows a skilled attacker with access to the targeted system to inject malicious code into processes or cause a denial-of-service (DoS) condition.

The flaw affects CCW Developer and Free Standard editions, versions 9.01.00 and earlier. A patch is included in versions 10.00 and 10.01.

The second high severity vulnerability was identified by Rockwell Automation in FactoryTalk Activation, a tool used for activating and managing Rockwell software and activation files. The tool is used by several products, including FactoryTalk, Arena, Emonitor, RSFieldBus, RSLinx, RSLogix, RSNetWorx, RSView32, SoftLogix and Studio 5000.

The security hole, CVE-2017-6015, is related to the improper handling of search paths and it can be exploited by a local user with limited rights to execute arbitrary code with elevated privileges.

The vulnerability affects FactoryTalk Activation 4.00.02 and prior, and it has been addressed with the release of version 4.01.

Rockwell customers that cannot immediately update their software have been provided mitigation instructions for both the CCW and FactoryTalk Activation flaws.
