CVE-2018-25233
WebDrive 18.00.5057 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long string in the username field during Secure WebDAV connection setup.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
