A vulnerability exists in Rockwell Automation FactoryTalk® Service Platform that allows a malicious user to obtain the service token and use it for authentication on another FTSP directory. This is due to the lack of digital signing between the FTSP service token and directory.  If exploited, a malicious user could potentially retrieve user information and modify settings without any authentication.
