32
FAUCET Score

CVE-2014-5435 is a critical arbitrary memory write vulnerability in the dual_onsrv.exe module of Honeywell Experion PKS R40x, R41x, and R43x, allowing for potential remote code execution or denial of service. With a CVSS score of 9.8, it presents a severe risk due to its network-based attack vector and low attack complexity, enabling full compromise of confidentiality, integrity, and availability. Despite its high severity and FAUCET Risk Score of 81/100, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage. Honeywell recommends upgrading to supported versions for unsupported EKPS installations.
