漏洞描述
中文描述:

Cisco Adaptive Security Appliances Software（ASA Software）是美国思科（Cisco）公司的一套防火墙和网络安全平台。该平台提供了对数据和网络资源的高度安全的访问等功能。 Cisco Adaptive Security Appliances Software 存在安全漏洞，该漏洞源于在生成加密密钥时受影响的硬件平台的 DRBG 中的熵不足。

英文描述:

A vulnerability in the deterministic random bit generator (DRBG), also known as pseudorandom number generator (PRNG), in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software for Cisco ASA 5506-X, ASA 5508-X, and ASA 5516-X Firewalls could allow an unauthenticated, remote attacker to cause a cryptographic collision, enabling the attacker to discover the private key of an affected device. This vulnerability is due to insufficient entropy in the DRBG for the affected hardware platforms 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.
