IBM Sterling File Gateway 2.2.0.0 through 6.0.3.1 could allow an authenticated user could manipulate cookie information and remove or add modules from the cookie to access functionality not authorized to.
Does this matter?
Lower severity and a low EPSS score (0.76%). Track it; it rarely justifies an emergency change on its own.
