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。 Cisco WLC Software中的Control and Provisioning of Wireless Access Points(CAPWAP)协议处理器存在输入验证错误漏洞,该漏洞源于程序没有充分验证CAPWAP数据包。攻击者可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 handler of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient validation of CAPWAP packets. An attacker could exploit this vulnerability by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to restart, resulting in a DoS condition.
