CVE-2026-20136
Estado: AnalizadaMedia (6)—
A vulnerability in the CLI of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, local attacker with administrative privileges to perform a command injection attack on the underlying operating system and elevate privileges to root.
This vulnerability is due to insufficient validation of user supplied input. An attacker could exploit this vulnerability by providing crafted input to a specific CLI command. A successful exploit could allow the attacker to elevate their privileges to root on the underlying operating system.
