CVE编号
CVE-2019-15261利用情况
暂无补丁情况
N/A披露时间
2019-10-17漏洞描述
Cisco Aironet接入点（AP）中的点对点隧道协议（PPTP）VPN数据包处理功能中的漏洞可能允许未经身份验证的远程攻击者重新加载受影响的设备，从而导致拒绝服务（DoS））状况。该漏洞是由于对通过受影响的AP的数据平面传递的通用路由封装（GRE）帧的验证不充分造成的。攻击者可以通过与易受攻击的AP关联，启动与任意PPTP VPN服务器的PPTP VPN连接并通过AP的数据平面发送恶意GRE帧来利用此漏洞。成功的利用可能使攻击者导致目标AP的内部进程崩溃，进而导致AP重新加载。 AP重新加载将导致与AP关联的客户端的DoS条件。解决建议
