漏洞描述
中文描述:
Cisco IOS XE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 Catalyst 9800 Series Wireless Controllers中的IOS XE Software的IEEE 802.11w Protected Management Frames处理存在输入验证错误漏洞。攻击者可通过发送伪造的802.11w PMF利用该漏洞终止有效用户对受影响设备的连接。
英文描述:
A vulnerability in the handling of IEEE 802.11w Protected Management Frames (PMFs) of Cisco Catalyst 9800 Series Wireless Controllers that are running Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to terminate a valid user connection to an affected device. The vulnerability exists because the affected software does not properly validate 802.11w disassociation and deauthentication PMFs that it receives. An attacker could exploit this vulnerability by sending a spoofed 802.11w PMF from a valid, authenticated client on a network adjacent to an affected device. A successful exploit could allow the attacker to terminate a single valid user connection to the affected device.
