CVE-2019-1728

6.7 MEDIUM 0.2% exploit odds Fix listed

What it is

A vulnerability in the Secure Configuration Validation functionality of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to run arbitrary commands at system boot time with the privileges of root. The vulnerability is due to a lack of proper validation of system files when the persistent configuration information is read from the file system. An attacker could exploit this vulnerability by authenticating to the device and overwriting the persistent configuration storage with malicious executable files. An exploit could allow the attacker to run arbitrary commands at system startup and those commands will run as the root user. The attacker must have valid administrative credentials for the device.
