Rockwell Automation reports this vulnerability affects the following Studio 5000 Logix Designer design, configuration hardware, and software products:
An attacker who achieves administrator access on a workstation running Studio 5000 Logix Designer could inject controller code undetectable to a user.
CVE-2022-1159 has been assigned to this vulnerability. A CVSS v3 base score of 7.7 has been assigned; the CVSS vector string is (AV:L/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H).
Sharon Brizinov and Tal Keren of Claroty reported this vulnerability to Rockwell Automation.
Rockwell Automation recommends users of the affected hardware and software take risk mitigation steps listed below. Users are encouraged, when possible, to combine this guidance with the general security guidelines for a comprehensive defense-in-depth strategy.
There is no direct mitigation for this vulnerability in the Logix Designer application. However, a detection method is available to determine if the user program residing in the controller is identical to what was downloaded. This user program verification can be done by the following:
To leverage these detection capabilities, users are directed to upgrade to:
This user program comparison must be performed on an uncompromised workstation.
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
