Cisco IOS XE Software Command Injection Vulnerability
漏洞描述
中文描述:
Cisco IOS和IOS XE都是美国思科（Cisco）公司的产品。CLI是其中的一个命令行界面。 Cisco IOS XE的CLI存在安全漏洞，该漏洞源于对特定CLI命令的参数验证不足所致。攻击者可利用该漏洞会使每次重新启动受影响的设备时都以root特权执行命令。
英文描述:
A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to inject a command to the underlying operating system that will execute with root privileges upon the next reboot of the device. The authenticated user must have privileged EXEC permissions on the device. The vulnerability is due to insufficient protection of values passed to a script that executes during device startup. An attacker could exploit this vulnerability by writing values to a specific file. A successful exploit could allow the attacker to execute commands with root privileges each time the affected device is restarted.
