CVE-2017-3839
An XML External Entity vulnerability in the web-based user interface of the Cisco Secure Access Control System (ACS) could allow an unauthenticated, remote attacker to have read access to part of the information stored in the affected system.
Does this matter?
Lower severity and a low EPSS score (1.55%). Track it; it rarely justifies an emergency change on its own.
