The vulnerabilities are due to insufficient protections of the secure boot process. An attacker could exploit these vulnerabilities by injecting code into specific files that are then referenced during the device boot process. A successful exploit could allow the attacker to break the chain of trust and inject code into the boot process of the device, which would be executed at each boot and maintain persistence across reboots."},{"lang":"es","value":"Múltiples vulnerabilidades en el proceso de inicio seguro de Cisco Adaptive Security Appliance (ASA) Software y Firepower Threat Defense (FTD) Software para Dispositivos Firepower 1000 Series y Firepower 2100 Series podrían permitir a un atacante local autenticado omitir el mecanismo de inicio seguro. Las vulnerabilidades son debido a protecciones insuficientes del proceso de arranque seguro. Un atacante podría explotar estas vulnerabilidades inyectando código en archivos específicos a los que luego se hace referencia durante el proceso de inicio del dispositivo. Una explotación con éxito podría permitir a un atacante romper la cadena de confianza e inyectar código en el proceso de arranque del dispositivo, que se ejecutaría en cada arranque y mantendría la persistencia entre los reinicios"}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":6.7,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":0.8,"impactScore":5.9}],"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":6.7,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":0.8,"impactScore":5.9}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:L/AC:L/Au:N/C:P/I:P/A:P","baseScore":4.6,"accessVector":"LOCAL","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":3.9,"impactScore":6.4,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-693"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-Other"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionStartIncluding":"9.8.0","versionEndExcluding":"9.8.4.26","matchCriteriaId":"E38D6F74-E407-4232-86C9-178AC3D00F1C"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionStartIncluding":"9.9.0","versionEndExcluding":"9.9.2.80","matchCriteriaId":"E16D2CA3-B494-4348-BF0C-03969D1423D0"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionStartIncluding":"9.10.0","versionEndExcluding":"9.10.1.43","matchCriteriaId":"7036D010-F764-4899-A7B3-456084FC1392"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionStartIncluding":"9.12.0","versionEndExcluding":"9.12.4.3","matchCriteriaId":"88977C36-3EF9-44FD-8406-2A223A8FDF4A"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionStartIncluding":"9.13.0","versionEndExcluding":"9.13.1.13","matchCriteriaId":"A4148D30-F285-4045-A017-82F5BF074233"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionStartIncluding":"9.14.0","versionEndExcluding":"9.14.1.15","matchCriteriaId":"8353B0CD-5C3F-4F18-966B-DB43DA92838E"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1010:*:*:*:*:*:*:*:*","matchCriteriaId":"018CB46C-D151-4D5C-9ED8-D5F57E2723CF"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1010:-:*:*:*:*:*:*:*","matchCriteriaId":"7FFE3880-4B85-4E23-9836-70875D5109F7"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1120:-:*:*:*:*:*:*:*","matchCriteriaId":"727A02E8-40A1-4DFE-A3A2-91D628D3044F"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1140:-:*:*:*:*:*:*:*","matchCriteriaId":"19F6546E-28F4-40DC-97D6-E0E023FE939B"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1150:-:*:*:*:*:*:*:*","matchCriteriaId":"EB3B0EC3-4654-4D90-9D41-7EC2AD1DDF99"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2110:-:*:*:*:*:*:*:*","matchCriteriaId":"52D96810-5F79-4A83-B8CA-D015790FCF72"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2120:-:*:*:*:*:*:*:*","matchCriteriaId":"16FE2945-4975-4003-AE48-7E134E167A7F"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2130:-:*:*:*:*:*:*:*","matchCriteriaId":"DCE7122A-5AA7-4ECD-B024-E27C9D0CFB7B"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2140:-:*:*:*:*:*:*:*","matchCriteriaId":"976901BF-C52C-4F81-956A-711AF8A60140"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*","versionEndIncluding":"6.2.2","matchCriteriaId":"2330600D-6AB1-4912-A595-2AE167853B93"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3.0","versionEndExcluding":"6.3.0.6","matchCriteriaId":"9D27DE97-510A-4761-8184-6940745B54E2"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4.0","versionEndExcluding":"6.4.0.10","matchCriteriaId"
