CVE-2014-5435
An arbitrary memory write vulnerability exists in the dual_onsrv.exe module in Honeywell Experion PKS R40x before R400.6, R41x before R410.6, and R43x before R430.2, that could lead to possible remote code execution or denial of service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
