This compromises the availability of all keys configured with external key storage and may result in an economic attack in which the attacker denies legitimate users access to keys while maintaining possession of an encrypted copy (blob) of the external key store for ransom. This attack has been dubbed reverse ransomware attack and may be executed via a physical connection to the CryptoServer or remote connection if SSH or remote access to LAN CryptoServer has been compromised. The Confidentiality and Integrity of the affected keys, however, remain untarnished."}, {"lang": "es", "value": "Los Controles de Acceso incorrectos del Security Officer (SO) en el proveedor PKCS11 R2 que se env\u00eda con el paquete del producto Utimaco CryptoServer HSM permite que un SO identificado en un espacio recupere los atributos de las claves marcadas como claves privadas en el almacenamiento de las claves externas, y tambi\u00e9n elimine las claves marcadas como claves privadas en el almacenamiento de las claves externas.
