Description

Multiple vulnerabilities in specific Cisco Identity Services Engine (ISE) CLI commands could allow an authenticated, local attacker to perform command injection attacks on the underlying operating system and elevate privileges to root. To exploit these vulnerabilities, an attacker must have valid Administrator privileges on the affected device. These vulnerabilities are due to insufficient validation of user-supplied input. An attacker could exploit these vulnerabilities by submitting a crafted CLI command. A successful exploit could allow the attacker to elevate privileges to root.
