That file is writable by an authenticated Redfish client through the `UpdateService.UploadSignKey` action, which stores the uploaded body verbatim after validating only that the multipart filename ends in `.pem`. An administrator, or any account with `firmware-update` privilege, can therefore replace the trust anchor with their own key, sign a malicious image with the matching private key, and have it pass verification. Family-A has no hardware root-of-trust (no PFR) to catch the substituted key.\u00A0\n\nThis was observed on H3C HDM Family-A G5 HDM 6.14.01. H3C HDM Family-A G3/G5 builds carrying the Redfish/DRE update tree appear to be affected. HDM2 uses a different update path and is not covered by this finding.","state":0,"publishedAt":"2026-10-13T14:17:54.265+00:00","modifiedAt":"2026-10-14T18:59:13.586+00:00","affected":[{"ecosystem":"Vendor product","name":"HDM Family-A G5","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"H3C\",\n                    \"product\": \"HDM Family-A G5\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"6.14.01\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N","score":3.1,"severity":"LOW"}],"references":["https://www.runzero.com/advisories/h3c-hdm-firmware-verification-key-replacement-cve-2026-65197"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-65197","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-65197","identifiers":["CVE-2026-65197"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
