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 RV110W、RV130、RV130W 和 RV215W 路由器存在缓冲区错误漏洞，该漏洞源于对传入 UPnP 流量的验证不当造成的。该漏洞可能允许未经身份验证的远程攻击者执行任意代码或导致受影响的设备意外重启，从而导致拒绝服务 (DoS) 。

英文描述:

A vulnerability in the Universal Plug-and-Play (UPnP) service of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of incoming UPnP traffic. An attacker could exploit this vulnerability by sending a crafted UPnP request to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a DoS condition. Cisco has not released software updates that address this vulnerability.
