漏洞描述
中文描述:
Cisco Aironet 1540 Series APs等都是美国思科（Cisco）公司的产品。Cisco Aironet 1540 Series APs是一款1540系列访问接入点产品。Cisco Aironet 1560 Series APs是一款1560系列访问接入点产品。Cisco Aironet 1800 Series APs是一款1800系列访问接入点产品。 多款Cisco产品中的内部数据包处理过程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。以下产品受到影响：Cisco Aironet 1540 Series APs；Aironet 1560 Series APs；Aironet 1800 Series APs；Aironet 2800 Series APs；Aironet 3800 Series APs。
英文描述:
A vulnerability in the internal packet processing of Cisco Aironet Series Access Points (APs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected AP if the switch interface where the AP is connected has port security configured. The vulnerability exists because the AP forwards some malformed wireless client packets outside of the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel. An attacker could exploit this vulnerability by sending crafted wireless packets to an affected AP. A successful exploit could allow the attacker to trigger a security violation on the adjacent switch port, which could result in a DoS condition. Note: Though the Common Vulnerability Scoring System (CVSS) score corresponds to a High Security Impact Rating (SIR), this vulnerability is considered Medium because a workaround is available and exploitation requires a specific switch configuration. There are workarounds that address this vulnerability.
