Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-20286 is a vulnerability in the cloud deployments of Cisco Identity Services Engine (ISE) on Amazon Web Services (AWS), Microsoft Azure, and Oracle Cloud Infrastructure (OCI). It stems from improperly generated credentials during the deployment process, causing different ISE deployments to share the same credentials if they use the same software release and cloud platform. This vulnerability only affects deployments where the Primary Administration node is hosted in the cloud. An attacker could exploit this vulnerability by extracting user credentials from a Cisco ISE instance deployed in the cloud and using them to access other ISE deployments across different cloud environments through unsecured ports. Successful exploitation could allow an unauthenticated, remote attacker to access sensitive data, execute limited administrative operations, modify system configurations, or disrupt services within the impacted systems.

Description: A vulnerability in Amazon Web Services (AWS), Microsoft Azure, and Oracle Cloud Infrastructure (OCI) cloud deployments of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to access sensitive data, execute limited administrative operations, modify system configurations, or disrupt services within the impacted systems. This vulnerability exists because credentials are improperly generated when Cisco ISE is being deployed on cloud platforms, resulting in different Cisco ISE deployments sharing the same credentials. These credentials are shared across multiple Cisco ISE deployments as long as the software release and cloud platform are the same. An attacker could exploit this vulnerability by extracting the user credentials from Cisco ISE that is deployed in the cloud and then using them to access Cisco ISE that is deployed in other cloud environments through unsecured ports. A successful exploit could allow the attacker to access sensitive data, execute limited administrative operations, modify system configurations, or disrupt services within the impacted systems. Note: If the Primary Administration node is deployed in the cloud, then Cisco ISE is affected by this vulnerability. If the Primary Administration node is on-premises, then it is not affected.
