漏洞描述
中文描述:
Cisco Firepower Threat Defense(FTD)是美国思科(Cisco)公司的一套提供下一代防火墙服务的统一软件。 Cisco Firepower Threat Defense 存在输入验证错误漏洞,该漏洞允许未经身份验证的远程攻击者可利用该漏洞触发重新加载受影响的设备,从而导致拒绝服务(DoS)状态。
英文描述:
A vulnerability in the software-based SSL/TLS message handler of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of SSL/TLS messages when the device performs software-based SSL decryption. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message through an affected device. SSL/TLS messages sent to an affected device do not trigger this vulnerability. A successful exploit could allow the attacker to cause a process to crash. This crash would then trigger a reload of the device. No manual intervention is needed to recover the device after the reload.
