Private-information exposure in Yokogawa Electric Corporation FAST/TOOLS R9.01 through R10.04 allows attackers to read saved form input. Affected web forms leave autocomplete enabled on input fields, permitting browsers to retain entered values instead of suppressing storage. A user must enter data in an affected form, and disclosure requires unauthorized access to the browser's retained data.
