This is not sufficient to verify that the macro was actually signed with the certificate. An adversary could therefore create an arbitrary certificate with a serial number and an issuer string identical to a trusted certificate which LibreOffice would present as belonging to the trusted author, potentially leading to the user to execute arbitrary code contained in macros improperly trusted. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions prior to 7.3.1."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-295"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2022-26305", "ASSIGNER": "security@documentfoundation.org"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 7.5, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "REQUIRED", "attackComplexity": "HIGH", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "HIGH"}, "impactScore": 5.9, "exploitabilityScore": 1.6}}, "publishedDate": "2022-07-25T15:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:libreoffice:libreoffice:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "7.2.7", "versionStartIncluding": "7.2.0"}, {"cpe23Uri": "cpe:2.3:a:libreoffice:libreoffice:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "7.3.2", "versionStartIncluding": "7.3.0"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2023-03-26T23:15Z"}
