漏洞描述
中文描述:
Cisco Catalyst 9200 Series Switches是美国思科（Cisco）公司的一款交换机。 Cisco Catalyst 9200系列交换机的Cisco IOS XE软件的Umbrella Connector组件存在安全漏洞，该漏洞源于解析DNS请求时没有足够的错误处理引起的。攻击者可利用该漏洞导致iosd进程崩溃，从而触发受影响设备的重新加载。
英文描述:
A vulnerability in the Umbrella Connector component of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches could allow an unauthenticated, remote attacker to trigger a reload, resulting in a denial of service condition on an affected device. The vulnerability is due to insufficient error handling when parsing DNS requests. An attacker could exploit this vulnerability by sending a series of malicious DNS requests to an Umbrella Connector client interface of an affected device. A successful exploit could allow the attacker to cause a crash of the iosd process, which triggers a reload of the affected device.
