漏洞描述
中文描述:
Cisco IOS XE Software是美国思科（Cisco）公司的一个操作系统。用于企业有线和无线访问，汇聚，核心和WAN的单一操作系统，Cisco IOS XE降低了业务和网络的复杂性。 Cisco IOS XE Software存在安全漏洞，该漏洞源于 Cisco UTD Snort IPS 引擎处理 HTTP 请求时对 HTTP 请求的验证不足。
英文描述:
A vulnerability in Cisco Unified Threat Defense (UTD) Snort Intrusion Prevention System (IPS) Engine for Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass configured security policies or cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of HTTP requests when they are processed by Cisco UTD Snort IPS Engine. An attacker could exploit this vulnerability by sending a crafted HTTP request through an affected device. A successful exploit could allow the attacker to trigger a reload of the Snort process. If the action in case of Cisco UTD Snort IPS Engine failure is set to the default, fail-open, successful exploitation of this vulnerability could allow the attacker to bypass configured security policies. If the action in case of Cisco UTD Snort IPS Engine failure is set to fail-close, successful exploitation of this vulnerability could cause traffic that is configured to be inspected by Cisco UTD Snort IPS Engine to be dropped.
