A local user can be impersonated when using federated authentication with Silent JIT Provisioning.

When the "Silent Just-In-Time Provisioning" feature is enabled for a federated identity provider (IDP) there is a risk that a local user store user's information may be replaced during the account provisioning process in cases where federated users share the same username as local users. There will be no impact on your deployment if any of the preconditions mentioned below are not met. Only when all the preconditions mentioned below are fulfilled could a malicious actor associate a targeted local user account with a federated IDP user account that they control. The Deployment should have: -An IDP configured for federated authentication with Silent JIT provisioning enabled. The malicious actor should have: -A fresh valid user account in the federated IDP that has not been used earlier. -Knowledge of the username of a valid user in the local IDP. -An account at the federated IDP matching the targeted local username.

WSO2 API Manager和WSO2 Identity Server（IS） 安全漏洞

WSO2 API Manager和WSO2 Identity Server（IS）都是美国WSO2公司的产品。WSO2 API Manager是一套API生命周期管理解决方案。WSO2 Identity Server是一款身份认证服务器。 WSO2 API Manager和WSO2 Identity Server存在安全漏洞，该漏洞源于启用联合身份提供者的静默即时配置功能时，若联合用户与本地用户共享相同用户名，则本地用户存储信息可能在账户配置过程中被替换，可能导致恶意攻击者将目标本地用户账户与其控制的联合
