CVE-2018-0443 (CNNVD-201810-982)
中文标题:
Cisco Wireless LAN Controller Software 资源管理错误漏洞
英文标题:
Cisco Wireless LAN Controller Software Control and Provisioning of Wireless Access Points Protocol Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Wireless LAN Controller(WLC)Software是美国思科(Cisco)公司的一套用于配置和管理WLC(无线局域网控制器)的软件。Control and Provisioning of Wireless Access Points(CAPWAP)是其中的一个无线接入点控制和配置组件。 Cisco WLC Software中的CAPWAP协议组件存在安全漏洞。远程攻击者可通过向Cisco WLC Software发送恶意的CAPWAP Discovery Request数据包利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol component of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper input validation on fields within CAPWAP Discovery Request packets by the affected device. An attacker could exploit this vulnerability by sending malicious CAPWAP Discovery Request packets to the Cisco WLC Software. A successful exploit could allow the attacker to cause the Cisco WLC Software to disconnect associated access points (APs). While the APs disconnect and reconnect, service will be unavailable for a brief period of time, resulting in a DoS condition.
