CVE-2013-2780
Siemens SIMATIC S7-1200 PLCs 2.x and 3.x allow remote attackers to cause a denial of service (defect-mode transition and control outage) via crafted packets to UDP port 161 (aka the SNMP port).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
