中文标题:
Cisco NX-OS Software 输入验证错误漏洞
英文标题:
Cisco NX-OS Software NX-API Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco NX-OS Software是美国思科(Cisco)公司的一套交换机使用的数据中心级操作系统软件。 Cisco NX-OS Software中的NX-API功能存在输入验证错误漏洞,该漏洞源于程序没有正确验证发送到NX-API的请求的HTTP头。远程攻击者可通过发送特制的HTTP请求利用该漏洞造成拒绝服务。以下产品及版本受到影响:Cisco MDS 9000 Series Multilayer Switches;Nexus 3000 Series Switches;Nexus 3500 Platform Switches;Nexus 3600 Platform Switches;Nexus 5500 Platform Switches;Nexus 5600 Platform Switches;Nexus 6000 Series Switches;Nexus 7000 Series Switches;Nexus 7700 Series Switches;Nexus 9000 Series Switches(standalone NX-OS mode);Nexus 9500 R-Series Switching Platform。
英文描述:
A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause an NX-API system process to unexpectedly restart. The vulnerability is due to incorrect validation of the HTTP header of a request that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API on an affected device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition in the NX-API service; however, the NX-OS device itself would still be available and passing network traffic. Note: The NX-API feature is disabled by default.
