漏洞描述
中文描述:
Cisco Aironet Series Access Points Software是美国思科(Cisco)公司的一套使用在Aironet无线接入点设备中的软件。 Cisco Aironet Series Access Points Software 存在安全漏洞,该漏洞允许未经身份验证的相邻攻击者可利用该漏洞在受影响的设备上造成拒绝服务。
英文描述:
A vulnerability in the multicast DNS (mDNS) gateway feature of Cisco Aironet Series Access Points Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of incoming mDNS traffic. An attacker could exploit this vulnerability by sending a crafted mDNS packet to an affected device through a wireless network that is configured in FlexConnect local switching mode or through a wired network on a configured mDNS VLAN. A successful exploit could allow the attacker to cause the access point (AP) to reboot, resulting in a DoS condition.
