      "value": "A vulnerability in the Image Signature Verification feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker with administrator-level credentials to install a malicious software patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. 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."

      "value": "Una vulnerabilidad en la funcionalidad Image Signature Verification del Cisco Firepower Threat Defense (FTD) Software, podr\u00eda permitir a un atacante remoto autenticado con credenciales de nivel de administrador instalar un parche de software malicioso sobre un dispositivo afectado. La vulnerabilidad es debido a una verificaci\u00f3n inapropiada de firmas digitales para im\u00e1genes de parches. Un atacante podr\u00eda explotar esta vulnerabilidad al dise\u00f1ar un parche de software sin firmar para omitir las comprobaciones de firmas y cargarlo sobre un dispositivo afectado. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir a un atacante iniciar una imagen de parche de software malicioso."
