Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
开放访问管理（OpenAM）是一种访问管理解决方案。在 16.1.1 版本之前，Liberty 的 Web 服务 SOAP 接收器允许未认证的远程请求通过 SOAPReceiver 和 DiscoveryService，将持久化条目写入用户的 Liberty 发现存储区以及共享的根域发现分支。服务器端的处理程序会绕过请求方的 LDAP 和身份访问控制列表（ACL），并且全局路径使用的是内部管理令牌。依赖 Liberty 发现数据的部署环境，随后可能会使用被篡改的服务路由记录或安全机制记录。该问题已在 16.1.1

Vulnerability Title
OpenAM Pre-auth User Profile Tampering via Anonymous SOAP Authn in Liberty IDPP/Discovery Endpoints
Source: CVE Program / CVE List V5
Vulnerability Description
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the Liberty Web Services SOAP receiver permits unauthenticated remote requests to write persistent entries through SOAPReceiver and DiscoveryService into a user's Liberty Discovery store and the shared root-realm Discovery branch. The server-side handlers bypass requester LDAP and identity ACLs, and the global path uses an internal administrative token. Deployments that consume Liberty discovery data can subsequently use manipulated service-routing or security-mechanism records. This issue is fixed in version 16.1.1.
