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. Honeywell strongly encourages and recommends all customers running unsupported versions of EKPS prior to R400 to upgrade to a supported version.
Weakness
Any condition where the attacker has the ability to write an arbitrary value to an arbitrary location, often as the result of a buffer overflow.
