Descriptions

A vulnerability in the CLI of Cisco ThousandEyes Enterprise Agent, Virtual Appliance installation type, could allow an authenticated, local attacker to elevate privileges on an affected device.
This vulnerability is due to insufficient input validation by the operating system CLI. An attacker could exploit this vulnerability by issuing certain commands using sudo. A successful exploit could allow the attacker to view arbitrary files as root on the underlying operating system. The attacker must have valid credentials on the affected device.

Cisco ThousandEyes Enterprise Agent Virtual Appliance version thousandeyes-va-64-18.04 0.218 has an insecure sudo configuration which permits a low-privilege user to read root-only files via the dig command without a password.
