CVE-2017-6017
A remote attacker could send a specially crafted set of packets to the PLC causing it to freeze, requiring the operator to physically press the reset button on the PLC in order to recover.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.81%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
