Vulnerability Title
Wazuh 4.0.0 < 4.14.6 Path Traversal DoS via Agent Enrollment
Source: CVE Program / CVE List V5
Vulnerability Description
Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows unauthenticated remote attackers to cause denial of service by enrolling an agent with a dot-sequence name such as ".." through the enrollment port. Attackers exploit insufficient validation in OS_IsValidName() and unsafe path concatenation in delete_diff() to resolve the traversal to the parent queue directory, causing its subdirectories to be removed and stopping all Wazuh services requiring manual recovery.

Wazuh 路径遍历漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
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至4.14.6之前版本存在路径遍历漏洞，该漏洞源于OS_IsValidName()验证不足及delete_diff()中不安全的路径拼接，可能导致未经身份验证的远程攻击者通过注册端口使用点序列名称（如“..”）注册代理，造成路径遍历，删除父队列目录的子目录，进而导致拒绝服务。
