漏洞描述
中文描述:
Cisco IOS和IOS XE Software都是美国思科（Cisco）公司为其网络设备开发的操作系统。 Cisco IOS和Cisco IOS XE Software中的Secure Shell (SSH)服务器存在访问控制错误漏洞，该漏洞源于程序缺少检测。攻击者可借助VRF实例的源地址利用该漏洞打开受影响的设备的SSH连接。
英文描述:
A vulnerability in the access control logic of the Secure Shell (SSH) server of Cisco IOS and IOS XE Software may allow connections sourced from a virtual routing and forwarding (VRF) instance despite the absence of the vrf-also keyword in the access-class configuration. The vulnerability is due to a missing check in the SSH server. An attacker could use this vulnerability to open an SSH connection to an affected Cisco IOS or IOS XE device with a source address belonging to a VRF instance. Once connected, the attacker would still need to provide valid credentials to access the device.
