CVE-2019-15261 (CNNVD-201910-1116)
中文标题:
Cisco Aironet Access Points 输入验证错误漏洞
英文标题:
Cisco Aironet Access Points Point-to-Point Tunneling Protocol Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Aironet Access Points (APs)中的Point-to-Point Tunneling Protocol (PPTP) VPN数据包处理功能存在输入验证错误漏洞。远程攻击者可利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in the Point-to-Point Tunneling Protocol (PPTP) VPN packet processing functionality in Cisco Aironet Access Points (APs) could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Generic Routing Encapsulation (GRE) frames that pass through the data plane of an affected AP. An attacker could exploit this vulnerability by associating to a vulnerable AP, initiating a PPTP VPN connection to an arbitrary PPTP VPN server, and sending a malicious GRE frame through the data plane of the AP. A successful exploit could allow the attacker to cause an internal process of the targeted AP to crash, which in turn would cause the AP to reload. The AP reload would cause a DoS condition for clients that are associated with the AP.
