漏洞描述
中文描述:
Cisco Access Points是美国思科（Cisco）公司的一款网络接入点设备。 Cisco Access Points 存在安全漏洞，该漏洞源于攻击者绕过VLAN后可以绕过Catalyst Access Point过滤规则实现发送恶意数据。
英文描述:
A vulnerability in the client forwarding code of multiple Cisco Access Points (APs) could allow an unauthenticated, adjacent attacker to inject packets from the native VLAN to clients within nonnative VLANs on an affected device. This vulnerability is due to a logic error on the AP that forwards packets that are destined to a wireless client if they are received on the native VLAN. An attacker could exploit this vulnerability by obtaining access to the native VLAN and directing traffic directly to the client through their MAC/IP combination. A successful exploit could allow the attacker to bypass VLAN separation and potentially also bypass any Layer 3 protection mechanisms that are deployed.
