Detailsinfo

A vulnerability was found in WSO2 Open Banking IAM, Identity Server as Key Manager and Identity Server (the affected version is unknown). It has been rated as critical. This issue affects an unknown code of the component Adaptive Authentication. The manipulation with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A cross-tenant authentication vulnerability exists in multiple WSO2 products due to improper cryptographic design in Adaptive Authentication. A single cryptographic key is used across all tenants to sign authentication cookies, allowing a privileged user in one tenant to forge authentication cookies for users in other tenants. Because the Auto-Login feature is enabled by default, this flaw may allow an attacker to gain unauthorized access and potentially take over accounts in other tenants. Successful exploitation requires access to Adaptive Authentication functionality, which is typically restricted to high-privileged users. The vulnerability is only exploitable when Auto-Login is enabled, reducing its practical impact in deployments where the feature is disabled.

The advisory is shared at security.docs.wso2.com. The identification of this vulnerability is CVE-2025-0663 since 01/23/2025. The exploitation is known to be easy. The attack needs to be initiated within the local network. Additional levels of successful authentication are required for exploitation. Neither technical details nor an exploit are publicly available.

Upgrading eliminates this vulnerability.
