中文标题:
Cisco IOS XE Software 资源管理错误漏洞
英文标题:
Cisco IOS XE Software for Cisco ASR 1000 Series 20-Gbps Embedded Services Processor IP ARP Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco IOS和IOS XE都是美国思科(Cisco)公司的一套为其网络设备开发的操作系统。 Cisco IOS XE Software IP Address Resolution Protocol (ARP) feature中存在安全漏洞,该漏洞源于受影响的设备达到平台限制而导致的错误处理不足所致,该漏洞允许攻击者可以通过向受影响的设备发送一系列恶意的IP ARP消息来利用此漏洞。
英文描述:
A vulnerability in the IP Address Resolution Protocol (ARP) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers with a 20-Gbps Embedded Services Processor (ESP) installed could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service condition. The vulnerability is due to insufficient error handling when an affected device has reached platform limitations. An attacker could exploit this vulnerability by sending a malicious series of IP ARP messages to an affected device. A successful exploit could allow the attacker to exhaust system resources, which would eventually cause the affected device to reload.
