An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image.Cisco has released software updates that address the vulnerability described in this advisory. There are no workarounds that address this vulnerability."}, {"lang": "es", "value": "Una vulnerabilidad en la funci\u00f3n de verificaci\u00f3n de firma de imagen del software Cisco SD-WAN podr\u00eda permitir que un atacante remoto autenticado con credenciales de nivel de administrador instale un parche de software malicioso en un dispositivo afectado. La vulnerabilidad se debe a una verificaci\u00f3n incorrecta de las firmas digitales para las im\u00e1genes de parches. Un atacante podr\u00eda aprovechar esta vulnerabilidad creando un parche de software sin firmar para eludir las comprobaciones de firmas y cargarlo en un dispositivo afectado. Una explotaci\u00f3n exitosa podr\u00eda permitir al atacante iniciar una imagen de parche de software malicioso. Cisco ha publicado actualizaciones de software que solucionan la vulnerabilidad descrita en este aviso. No existen workarounds que solucionen esta vulnerabilidad."}], "lastModified": "2024-11-21T05:44:24.867", "sourceIdentifier": "[email protected]"}
