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802.11 Generic Advertisement Service (GAS)帧处理功能存在缓冲区错误漏洞，该漏洞源于程序没有对802.11 GAS帧进行充分的验证。远程攻击者可通过向无线接入点发送特制的802.11 GAS帧利用该漏洞造成设备重新加载，导致拒绝服务。

英文描述:

A vulnerability in the 802.11 Generic Advertisement Service (GAS) frame processing function of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS). The vulnerability is due to incomplete input validation of the 802.11 GAS frames that are processed by an affected device. An attacker could exploit this vulnerability by sending a crafted 802.11 GAS frame over the air to an access point (AP), and that frame would then be relayed to the affected WLC. Also, an attacker with Layer 3 connectivity to the WLC could exploit this vulnerability by sending a malicious 802.11 GAS payload in a Control and Provisioning of Wireless Access Points (CAPWAP) packet to the device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS.
