CVE-2019-18247
An attacker may use a specially crafted message to force Relion 650 series (versions 1.3.0.5 and prior) or Relion 670 series (versions 1.2.3.18, 2.0.0.11, 2.1.0.1 and prior) to reboot, which could cause a denial of service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
