Description
An improper authorization vulnerability exists in the Rockwell Automation affected products that could allow an unauthorized user to sign in. While removal of all role mappings is unlikely, it could occur in the case of unexpected or accidental removal by the administrator. If exploited, an unauthorized user could access data they previously but should no longer have access to.
