Descriptions
A vulnerability in the Deterministic Random Bit Generator (DRBG), also known as Pseudorandom Number Generator (PRNG), used in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a cryptographic collision, enabling the attacker to discover the private key of an affected device. The vulnerability is due to insufficient entropy in the DRBG when generating cryptographic keys. An attacker could exploit this vulnerability by generating a large number of cryptographic keys on an affected device and looking for collisions with target devices. A successful exploit could allow the attacker to impersonate an affected target device or to decrypt traffic secured by an affected key that is sent to or from an affected target device.
Una vulnerabilidad en el Deterministic Random Bit Generator (DRBG), conocido como Pseudorandom Number Generator (PRNG), utilizado en los programas Adaptive Security Appliance (ASA) y Firepower Threat Defense (FTD) de Cisco, podría permitir que un atacante remoto no identificado genere una colisión criptográfica, que permite al atacante descubrir la clave privada de un dispositivo afectado. La vulnerabilidad se debe a una entropía insuficiente en la DRBG al generar claves criptográficas. Un atacante podría atacar esta vulnerabilidad al generar una gran cantidad de claves criptográficas en un dispositivo afectado y provocar colisiones con los dispositivos de destino. Una operación exito podría permitir al atacante hacerse pasar por un dispositivo de destino afectado o descifrar el tráfico protegido por una clave afectada que se envía desde un dispositivo de destino afectado.
