Overview

CVE-2025-20282 is a critical-severity vulnerability. It was published on June 25, 2025 and has a CVSS 3.1 base score of 10.0 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 10.0, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

A vulnerability in an internal API of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to upload arbitrary files to an affected device and then execute those files on the underlying operating system as root.

This vulnerability is due a lack of file validation checks that would prevent uploaded files from being placed in privileged directories on an affected system. An attacker could exploit this vulnerability by uploading a crafted file to the affected device. A successful exploit could allow the attacker to store malicious files on the affected system and then execute arbitrary code or obtain root privileges on the system.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
