Summary
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 Read-only-level privileges or higher 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.
