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 Appliance (ASA) Software 存在缓冲区错误漏洞,该漏洞源于思科自适应安全设备(ASA)软件和火力威胁防御(FTD)软件VPN接口的边界错误。以下产品及版本受到影响:Cisco Adaptive Security Appliance (ASA) Software: before 9.8.4.35, 9.9.2.85, 9.12.4.18, 9.13.1.21, 9.14.2.13, 9.15.1.15 。

英文描述:

Multiple vulnerabilities in Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to lack of proper input validation of the HTTPS request. An attacker could exploit these vulnerabilities by sending a crafted HTTPS request to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: This vulnerability affects only specific AnyConnect and WebVPN configurations. For more information, see the Vulnerable Products section.
