Si el archivo está presente y contiene una clave pública compatible, el contenedor abrirá el puerto 22 y habilitará sshd con las claves proporcionadas como claves autorizadas para el inicio de sesión de root. Un atacante podría agregar fácilmente sus propias claves y obtener control total sobre el sistema sin activar el mecanismo de \"\"measured boot\"\" implementado por EVE OS y sin marcar el dispositivo como \"\"UUD\"\" (\"\"Actualización Desconocida Detectada\"\"). Esto se debe a que la partición “/config” no está protegida por “measured boot”, es mutable y no está cifrada de ninguna manera. Un atacante puede obtener control total sobre el dispositivo sin cambiar los valores de PCR, por lo que no activará el mecanismo de \"\"measured boot\"\" y tendrá acceso completo a \"\"vault\"\". Nota: Este problema se solucionó parcialmente en estos commits (después de la divulgación a Zededa), donde la medición de la partición de configuración se agregó a PCR13:\n• aa3501d6c57206ced222c33aea15a9169d629141 \n• 5fef4d92e75838cc78010edaed5247dfbdae1889. \nEste problema se hizo viable en la versión 9.0.0 cuando el cálculo se trasladó a PCR14, pero no se incluyó en el \"\"measured boot\"\"."}],"metrics":{"cvssMetricV31":[{"source":"cve@asrg.io","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.0,"impactScore":6.0},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.0,"impactScore":6.0}]},"weaknesses":[{"source":"cve@asrg.io","type":"Secondary","description":[{"lang":"en","value":"CWE-522"},{"lang":"en","value":"CWE-922"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-522"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linuxfoundation:edge_virtualization_engine:*:*:*:*:*:*:*:*","versionEndExcluding":"8.6.0","matchCriteriaId":"A569C358-B746-494B-A5EE-15D38BD74AB2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linuxfoundation:edge_virtualization_engine:*:*:*:*:*:*:*:*","versionStartIncluding":"9.0.0","versionEndExcluding":"9.5.0","matchCriteriaId":"D19A1245-092C-478C-BB01-23F91A227B3F"}]}]}],"references":[{"url":"https://asrg.io/security-advisories/cve-2023-43631/","source":"cve@asrg.io"},{"url":"https://asrg.io/security-advisories/cve-2023-43631/","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
