CVE-2018-19021
A specially crafted script could bypass the authentication of a maintenance port of Emerson DeltaV DCS Versions 11.3.1, 11.3.2, 12.3.1, 13.3.1, 14.3, R5.1, R6 and prior, which may allow an attacker to cause a denial of service.
Does this matter?
Lower severity and a low EPSS score (0.72%). Track it; it rarely justifies an emergency change on its own.
