漏洞描述
中文描述:
Cisco 路由器是美国思科（Cisco）公司的一个路由器。 Cisco RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers 存在安全漏洞，该漏洞允许经过身份验证的本地攻击者可利用该漏洞运行任意命令。
英文描述:
A vulnerability in the internal message processing of Cisco RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an authenticated, local attacker to run arbitrary commands with root privileges on the underlying operating system (OS). This vulnerability exists because an internal messaging service does not properly sanitize input. An attacker could exploit this vulnerability by first authenticating to the device and then sending a crafted request to the internal service. A successful exploit could allow the attacker to run arbitrary commands with root privileges on the underlying OS. To exploit this vulnerability, the attacker must have valid Administrator credentials for the device.
