Wazuh是美国Wazuh公司开源的一款安全检测与威胁分析平台。 Wazuh 4.0.0版本至4.14.5之前版本存在授权问题漏洞，该漏洞源于授权问题，低权限只读API用户可通过GET /manager/configuration?raw=true获取集群密钥，并利用泄露的Fernet密钥冒充集群worker提交恶意分布式API请求，由于主节点信任worker提供的授权上下文，可能导致攻击者创建用户、分配管理员角色、访问凭据和API令牌、修改配置及跨代理执行操作。

Vulnerability Title
Wazuh Manager dapi RBAC Bypass Allows Privilege Escalation
Source: CVE Program / CVE List V5
Vulnerability Description
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.5, Wazuh Manager allows a low-privilege read-only API user with manager:read permission to retrieve the cluster key from the element in ossec.conf through GET /manager/configuration?raw=true. An attacker with network access to TCP port 1516 can use the disclosed Fernet key to impersonate a cluster worker and submit distributed API requests containing attacker-controlled rbac_permissions with rbac_mode set to black. Because the master trusts the worker-supplied authorization context, the attacker can create users, assign administrator roles, access credentials and API tokens, modify configuration, and execute actions across agents. This issue is fixed in version 4.14.5.
