Technical ContextAI · show details

This vulnerability is classified under CWE-298. The silent Just-In-Time (JIT) provisioning feature in federated authentication implementations fails to properly segregate user roles during account creation when a federated user shares a username with a local user. This allows the provisioning process to overwrite existing roles of local users with roles assigned to the federated user. Exploitation requires a federated identity provider (IDP) with silent JIT provisioning enabled and an attacker's knowledge of a local user's username. When these conditions are met, a malicious individual can leverage the JIT provisioning process to modify the roles of local users. The overwritten roles are limited to those defined within the federated IDP, typically granting minimal access rights unless explicitly configured otherwise by the federated IDP administrator. Affected products include: Wso2 Wso2 Api Manager, Wso2 Wso2 Identity Server, Wso2 Wso2 Identity Server As Key Manager, Wso2 Wso2 Open Banking Am, Wso2 Wso2 Open Banking Iam.
