Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family CAPWAP Denial of Service Vulnerabilities
漏洞描述
中文描述:
Cisco IOS和IOS XE都是美国思科（Cisco）公司的产品。CLI是其中的一个命令行界面。 Cisco Catalyst 9800系列无线控制器的Cisco IOS XE软件的控制和供应无线接入点（CAPWAP）协议存在安全漏洞，该漏洞源于CAPWAP数据包验证不足所致。攻击者可利用该漏洞导致受影响的设备崩溃并重新加载，从而导致受影响的设备上出现DoS状况。
英文描述:
Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition of an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit these vulnerabilities by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition on the affected device.
