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4.14.6之前版本和5.0.0-beta1版本至5.0.0-beta2之前版本存在路径遍历漏洞，该漏洞源于对文件路径处理不当，未对攻击者控制的文件名进行规范化和限制，可能导致经过集群认证的攻击者利用绝对路径或路径遍历删除WAZUH_PATH之外的文件，从而禁用管理器、使API令牌失效并破坏集群和API连接。

Vulnerability Title
Wazuh: Arbitrary File Deletion via Cluster Protocol – Incomplete Path Validation in end_receiving_file()
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 4.14.6 and 5.0.0-beta2, WazuhCommon.end_receiving_file() in framework/wazuh/core/cluster/common.py allows a cluster-authenticated node to delete files outside WAZUH_PATH. A syn_i_w_m_e request with an unknown task_id reaches the cleanup branch, where an attacker-controlled filename is passed to os.path.join without canonicalization or confinement. Absolute paths and traversal sequences can therefore target files such as ossec.conf, jwt_secret.json, TLS certificates, and ruleset files that are accessible to the Wazuh manager process. Deletion can disable the manager, invalidate API tokens, or disrupt cluster and API connectivity. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.
