descriptionThe version of Microsoft Edge installed on the remote Windows host is missing Cumulative Security Update 3199057. It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user.
