漏洞描述
中文描述:
Cisco Enterprise NFV Infrastructure Software（NFVIS）是美国思科（Cisco）公司的一套NVF基础架构软件平台。该平台可以通过中央协调器和控制器实现虚拟化服务的全生命周期管理。 Cisco Enterprise NFV Infrastructure Software 存在授权问题漏洞，该漏洞源于对传递给身份验证脚本的用户提供的输入的验证不完整。攻击者可以通过向身份验证请求中注入参数来绕过身份验证并以管理员身份登录受影响的设备。
英文描述:
A vulnerability in the TACACS+ authentication, authorization and accounting (AAA) feature of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an unauthenticated, remote attacker to bypass authentication and log in to an affected device as an administrator. This vulnerability is due to incomplete validation of user-supplied input that is passed to an authentication script. An attacker could exploit this vulnerability by injecting parameters into an authentication request. A successful exploit could allow the attacker to bypass authentication and log in as an administrator to the affected device.
