漏洞描述
中文描述:
Cisco Wireless LAN Controller（WLC）是美国思科（Cisco）公司的一款无线局域网控制器产品。该产品在无线局域网中提供安全策略、入侵检测等功能。 Cisco Wireless LAN Controller 存在安全漏洞，该漏洞源于AireOS 软件的内存缓冲区中存在漏洞，未经身份验证的相邻攻击者可能会导致内存泄漏，最终导致设备重新启动。
英文描述:
A vulnerability in the memory buffer of Cisco Wireless LAN Controller (WLC) AireOS Software could allow an unauthenticated, adjacent attacker to cause memory leaks that could eventually lead to a device reboot. This vulnerability is due to memory leaks caused by multiple clients connecting under specific conditions. An attacker could exploit this vulnerability by causing multiple wireless clients to attempt to connect to an access point (AP) on an affected device. A successful exploit could allow the attacker to cause the affected device to reboot after a significant amount of time, resulting in a denial of service (DoS) condition.
