Title

Cisco Wireless LAN Controller拒绝服务漏洞（CNVD-2017-32923）

Description

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。 WLC中的Wireless Access Points (CAPWAP) Discovery Request解析功能的Control and Provisioning存在拒绝服务漏洞，该漏洞源于程序未能对CAPWAP Discovery Request数据包中的字段执行充分的输入验证。远程攻击者可通过向受影响的设备发送特制的CAPWAP Discovery Request数据包利用该漏洞造成拒绝服务（设备重启）。

CVE-2017-12280 (GCVE-0-2017-12280)

Vulnerability from cvelistv5 – Published: 2017-11-02 16:00 – Updated: 2024-08-05 18:36

Summary

A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) Discovery Request parsing functionality of Cisco Wireless LAN Controllers could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete input validation of fields in CAPWAP Discovery Request packets by the affected device. An attacker could exploit this vulnerability by sending crafted CAPWAP Discovery Request packets to an affected device. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition. Cisco Bug IDs: CSCvb95842.
