Title

Cisco Aironet存在拒绝服务漏洞（CNVD-2018-08990）

Description

Cisco Aironet 1810、1830和1850 Series Access Points都是美国思科（Cisco）公司的不同系列的无线接入点设备。Mobility Express Software是运行在其中的一套管理控制软件。 Cisco Aironet 1810、1830和1850 Series Access Points中的Mobility Express Software 8.4.100.0版本、8.5.103.0版本和8.5.105.0版本的Point-to-Point Tunneling Protocol功能的实现存在输入验证漏洞，该漏洞源于程序未能充分的校验通过受影响访问接入点数据层的通用路由封装（GRE）协议帧。远程攻击者可通过向受影响访问接入点创建PPTP连接并发送恶意的GRE帧利用该漏洞造成拒绝服务。

CVE-2018-0234 (GCVE-0-2018-0234)

Vulnerability from cvelistv5 – Published: 2018-05-02 22:00 – Updated: 2024-11-29 15:13

Summary

A vulnerability in the implementation of Point-to-Point Tunneling Protocol (PPTP) functionality in Cisco Aironet 1810, 1830, and 1850 Series Access Points 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 access point. An attacker could exploit this vulnerability by initiating a PPTP connection to an affected access point from a device that is registered to the same wireless network as the access point and sending a malicious GRE frame through the data plane of the access point. A successful exploit could allow the attacker to cause the NSS core process on the affected access point to crash, which would cause the access point to reload and result in a DoS condition. This vulnerability affects Cisco Aironet 1810, 1830, and 1850 Series Access Points that are running Cisco Mobility Express Software Release 8.4.100.0, 8.5.103.0, or 8.5.105.0 and are configured as a master, subordinate, or standalone access point. Cisco Bug IDs: CSCvf73890.

The vulnerability is due to insufficient validation of Generic Routing Encapsulation (GRE) frames that pass through the data plane of an affected access point. An attacker could exploit this vulnerability by initiating a PPTP connection to an affected access point from a device that is registered to the same wireless network as the access point and sending a malicious GRE frame through the data plane of the access point. A successful exploit could allow the attacker to cause the NSS core process on the affected access point to crash, which would cause the access point to reload and result in a DoS condition. This vulnerability affects Cisco Aironet 1810, 1830, and 1850 Series Access Points that are running Cisco Mobility Express Software Release 8.4.100.0, 8.5.103.0, or 8.5.105.0 and are configured as a master, subordinate, or standalone access point.
