漏洞描述
中文描述:
Cisco Small Business是美国思科（Cisco）公司的一个交换机。 Cisco Small Business 交换机 存在输入验证错误漏洞，该漏洞源于web管理页面对HTTP请求的验证不当造成的。攻击者可利用该漏洞通过向受影响的设备发送精心制作的HTTP请求导致dos。
英文描述:
A vulnerability in the web-based management interface of Cisco Small Business 200 Series Smart Switches, Cisco Small Business 300 Series Managed Switches, and Cisco Small Business 500 Series Stackable Managed Switches could allow an unauthenticated, remote attacker to render the web-based management interface unusable, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to cause a permanent invalid redirect for requests sent to the web-based management interface of the device, resulting in a DoS condition.
