Detailsinfo

A vulnerability was found in Cisco Identity Services Engine Software. It has been rated as critical. Affected by this issue is an unknown part. The manipulation with an unknown input leads to a hard-coded password vulnerability. Using CWE to declare the problem leads to CWE-259. The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound communication to external components. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at sec.cloudapps.cisco.com. This vulnerability is handled as CVE-2025-20286 since 10/10/2024. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 10/16/2025). This vulnerability is assigned to T1078.001 by the MITRE ATT&CK project.
