"According to its self-reported version, Cisco Identity Services Engine is affected by a command injection
vulnerability. A vulnerability in a specific Cisco ISE CLI command could allow an authenticated, local attacker to
perform command injection attacks on the underlying operating system and elevate privileges to root. To exploit this
vulnerability, an attacker must have valid Administrator-level privileges on the affected device. This vulnerability is
due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by submitting a
crafted CLI command. A successful exploit could allow the attacker to elevate privileges to root. (CVE-2023-20170)
