Descriptions
Brocade Fabric OS (FOS) hardware
platforms running any version of Brocade Fabric OS software, which
supports the license string format; contain cryptographic
issues that could allow for the installation of forged or fraudulent
license keys. This would allow attackers or a malicious party to forge a
counterfeit license key that the Brocade Fabric OS platform would
authenticate and activate as if it were a legitimate license key.
Plataformas de hardware Brocade Fabric OS (FOS) que ejecutan cualquier versión del software Brocade Fabric OS, que admita el formato de cadena de licencia; contienen problemas criptográficos que podrían permitir la instalación de claves de licencia falsificadas o fraudulentas. Esto permitiría a los atacantes o a una parte malintencionada falsificar una clave de licencia falsa que la plataforma Brocade Fabric OS autenticaría y activaría como si fuera una clave de licencia legítima.
