Cisco has released patches to address three vulnerabilities with public exploit code in its Identity Services Engine (ISE) and Customer Collaboration Platform (CCP) solutions.

The most severe of the three is a critical static credential vulnerability tracked as CVE-2025-20286, found by GMO Cybersecurity's Kentaro Kawane in Cisco ISE. This identity-based policy enforcement software provides endpoint access control and network device administration in enterprise environments.

The vulnerability is due to improperly generated credentials when deploying Cisco ISE on cloud platforms, resulting in shared credentials across different deployments.

Unauthenticated attackers can exploit it by extracting user credentials from Cisco ISE cloud deployments and using them to access installations in other cloud environments. However, as Cisco explained, threat actors can exploit this flaw successfully only if the Primary Administration node is deployed in the cloud.

"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," the company explained.
