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 Catalyst 9000 Family Wireless Controllers CAPWAP Denial of Service Vulnerabilities
漏洞描述
中文描述:
Cisco IOS XE Software是美国思科(Cisco)公司的一个操作系统。用于企业有线和无线访问,汇聚,核心和WAN的单一操作系统,Cisco IOS XE降低了业务和网络的复杂性。 Cisco IOS XE Software 存在安全漏洞,该漏洞源于对 CAPWAP 数据包的验证不足。攻击者可利用该漏洞向受影响的设备发送畸形CAPWAP包导致设备崩溃和重新加载,从而导致DoS。
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 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit the 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.
