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IAPP消息的处理存在输入验证错误漏洞，该漏洞源于网络系统或产品未对输入的数据进行正确的验证。
英文描述:
A vulnerability in the handling of Inter-Access Point Protocol (IAPP) messages by Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability exist because the software improperly validates input on fields within IAPP messages. An attacker could exploit the vulnerability by sending malicious IAPP messages to an affected device. A successful exploit could allow the attacker to cause the Cisco WLC Software to reload, resulting in a DoS condition. Software versions prior to 8.2.170.0, 8.5.150.0, and 8.8.100.0 are affected.
