A BIOS vendor test key is present in the UEFI Secure Boot key database. This could allow a local attacker with physical or administrative access to the device to boot an operating system or UEFI application signed with that test key, bypassing UEFI Secure Boot protections even when Secure Boot is enabled, potentially leading to a full loss of confidentiality, integrity, and availability of the device.","state":0,"publishedAt":"2026-10-13T09:18:54.197+00:00","modifiedAt":"2026-10-14T19:31:07.576+00:00","affected":[{"ecosystem":"Vendor product","name":"SIMATIC IPC BX-21A","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Siemens\",\n                    \"product\": \"SIMATIC IPC BX-21A\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"V31.01.13\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unknown\"\n                }"},{"ecosystem":"Vendor product","name":"SIMATIC IPC RW-543A","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Siemens\",\n                    \"product\": \"SIMATIC IPC RW-543A\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"V1.1.4\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unknown\"\n                }"},{"ecosystem":"Vendor product","name":"SIMATIC IPC227G / IPC277G / IPC277G PRO / IPC327G / IPC377G","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Siemens\",\n                    \"product\": \"SIMATIC IPC227G / IPC277G / IPC277G PRO / IPC327G / IPC377G\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"V28.01.15\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unknown\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","score":7.7,"severity":"HIGH"},{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.4,"severity":"HIGH"}],"references":["https://cert-portal.siemens.com/productcert/html/ssa-159454.html"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-72895","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-72895","identifiers":["CVE-2026-72895"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
