CVE-2014-5074
Siemens SIMATIC S7-1500 CPU devices with firmware before 1.6 allow remote attackers to cause a denial of service (device restart and STOP transition) via crafted TCP packets.
HIGH 7.1EPSS 9.70%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.70%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
