Vulnerability Title
Wazuh cluster DAPI arbitrary callable deserialization and RBAC context injection allow a cluster peer to execute privileged functions on the master node
Vulnerability Description
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to version 4.14.5, issues in the Cluster Distributed API (DAPI) handling allow a cluster peer, or any actor able to authenticate to the cluster channel using the shared cluster key, to make the master node deserialize an attacker-controlled callable and execute it under an attacker-controlled RBAC context. The cluster code in `framework/wazuh/core/cluster/common.py` deserializes JSON with `as_wazuh_object()`, which resolves any callable whose top-level package is wazuh or api (an overly broad allowlist controlled only by `ALLOWED_CALLABLES_PACKAGES`), and DAPI requests handled in framework/wazuh/core/cluster/dapi/dapi.py accept a client-supplied rbac_permissions value that `run_local()` applies as the global RBAC context, so supplying an rbac_mode of black causes authorization checks for expose_resources-protected functions to pass without any legitimate permission assignment. Combined, these allow privileged administrative actions on the master node such as arbitrary file writes under WAZUH_PATH, creation of new API users, and tampering with security.yaml, and can be chained into full manager compromise. This issue has been fixed in version 4.14.5.

Vulnerability Title
Wazuh 反序列化注入漏洞
Vulnerability Description
Wazuh是美国Wazuh公司开源的一个应用软件。用于收集,汇总,索引和分析安全数据,帮助组织检测入侵,威胁和行为异常。 Wazuh 4.14.5之前版本存在反序列化注入漏洞,该漏洞源于集群分布式API(DAPI)处理中的反序列化问题,允许集群对等方或任何能够使用共享集群密钥通过集群通道进行身份验证的行为者使主节点反序列化攻击者控制的可调用对象并在攻击者控制的RBAC环境下执行,从而导致授权检查绕过,最终可能造成在主节点上执行特权管理操作,例如在WAZUH_PATH下写入任意文件、创建新的API用户以及篡
