A vulnerability in a specific API of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to execute arbitrary code on the underlying operating system as root. This vulnerability is due to insufficient validation of user-supplied input. An attacker with valid credentials could exploit this vulnerability by submitting a crafted API request. A successful exploit could allow the attacker to execute commands as the root user. To exploit this vulnerability, the attacker must have valid high-privileged credentials.
Conclusion & alert: CVE-2025-20283 is rated Moderate Risk (51.7/100): CVSS Medium severity, with medium exploitation likelihood (EPSS 0.70%). Mandatory action: Review affected assets and schedule remediation.
