A vulnerability in Cisco IOx application hosting environment of Cisco IOS XE Software could allow an authenticated, remote attacker to inject commands into the underlying operating system as the root user. This vulnerability is due to incomplete validation of fields in the application packages loaded onto IOx. An attacker could exploit this vulnerability by creating a crafted application .tar file and loading it onto the device. A successful exploit could allow the attacker to perform command injection into the underlying operating system as the root user.
