AI description

Automated description summarized from trusted sources.

CVE-2025-20337 is a vulnerability in a specific API of Cisco ISE (Identity Services Engine) and Cisco ISE-PIC (ISE Passive Identity Connector). It could allow an unauthenticated, remote attacker to execute arbitrary code on the underlying operating system as root. The attacker doesn't need any valid credentials to exploit this vulnerability. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit it by submitting a crafted API request. Successful exploitation could allow the attacker to obtain root privileges on an affected device. This affects Cisco ISE and ISE-PIC releases 3.3 and 3.4, regardless of device configuration.
