CVE-2023-6837

Summary

CVE-2023-6837 is a vulnerability affecting multiple WSO2 products that allows for user impersonation through Just-in-Time (JIT) provisioning. The vulnerability can only be exploited if certain conditions are met, including the use of an Identity Provider (IDP) for federated authentication with JIT provisioning enabled, and a service provider that utilizes this IDP with the "Assert identity using mapped local subject identifier" flag activated. A malicious actor requires a fresh valid user account in the federated IDP and knowledge of a valid user's username in the local IDP to perform user impersonation during the JIT provisioning flow.
