Title: Cisco Wireless LAN Controller Software权限提升漏洞

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。

Cisco Wireless LAN Controller Software存在权限提升漏洞，该漏洞是由于在从Cisco TrustSec域内的一个服务集标识符（SSID）到另一个服务集标识符（SSID）的无线漫游期间动态分配安全组标签（SGT）。攻击者利用此漏洞可以通过尝试从域内的其他SSID获取SGT。成功利用可能允许攻击者获得在正常情况下应禁止的特权网络访问。

5.4 (Medium) - CVSS:3.0/AV:A/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

CWE

CWE-284

Summary

A vulnerability in the authentication and authorization checking mechanisms of Cisco Wireless LAN Controller (WLC) Software could allow an authenticated, adjacent attacker to gain network access to a Cisco TrustSec domain. Under normal circumstances, this access should be prohibited. The vulnerability is due to the dynamic assignment of Security Group Tags (SGTs) during a wireless roam from one Service Set Identifier (SSID) to another within the Cisco TrustSec domain. An attacker could exploit this vulnerability by attempting to acquire an SGT from other SSIDs within the domain. Successful exploitation could allow the attacker to gain privileged network access that should be prohibited under normal circumstances.
