Quick assessment

Affected
Cisco Cisco Small Business RV Series Router Firmware
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Cisco Small Business是美国思科（Cisco）公司的一个交换机。 Cisco Small Business路由器存在缓冲区错误漏洞，该漏洞源于经过身份验证的远程攻击者利用其web管理界面对传入的HTTP数据包中user字段验证不足造成的。攻击者可以通过向基于web的管理界面发送精心设计的请求导致其可以使用root权限在受影响的设备上执行任意命令，或者导致设备意外重启，从而导致拒绝服务。以下产品受到影响：RV110W、RV130、RV130W、RV215W。

Vulnerability Title
Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerabilities
Source: CVE Program / CVE List V5
Vulnerability Description
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device or cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker could exploit these vulnerabilities by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges or to cause the device to restart unexpectedly, resulting in a DoS condition. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities.
