CVE-2019-1729

A vulnerability in the CLI implementation of a specific command used for image maintenance for Cisco NX-OS Software could allow an authenticated, local attacker to overwrite any file on the file system including system files. These file overwrites by the attacker are accomplished at the root privilege level. The vulnerability occurs because there is no verification of user-input parameters and or digital-signature verification for image files when using a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device and issuing a command at the CLI. Because an exploit could allow the attacker to overwrite any file on the disk, including system files, a denial of service (DoS) condition could occur. The attacker must have valid administrator credentials for the affected device to exploit this vulnerability.
