Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Wazuh 是一个开源安全平台，为端点和云工作负载提供统一的 XDR（扩展检测与响应）和 SIEM（安全信息与事件管理）防护。在 4.2.0 至 4.14.6 版本中，多个活动响应脚本将受攻击者影响的警报字段传递给具有特权（以 root 身份运行）的系统命令，而未对其格式进行校验，从而导致参数注入漏洞，影响作为 root 运行的工具。 在八个处理 字段的脚本中，有五个—— 、 、 、 和 ——省略了对非 IP 输入进行拒绝的 检查。此外， 脚本将 字段传递给 / 命令，仅通过与 "root" 进行简单比较来校验。

Vulnerability Title
Wazuh: Missing input validation in multiple active response scripts allows argument injection
Source: CVE Program / CVE List V5
Vulnerability Description
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.2.0 through 4.14.6, multiple active response scripts pass attacker-influenced alert fields to privileged system commands without validating their format, allowing argument injection into tools that run as root. Five of the eight scripts that handle the srcip field, route-null.c, netsh.c, pf.c, npf.c, and ipfw.c, omit the get_ip_version() check that rejects non-IP input, and disable-account.c passes the dstuser field to passwd/chuser with only a comparison against "root". An attacker who can inject crafted log events, for example via syslog, can supply srcip or dstuser values that, when an active response rule triggers, are passed unvalidated to firewall and account-management commands such as pfctl, npfctl, ipfw, route, netsh, and passwd. This enables injecting additional command arguments, and on Windows the unquoted CreateProcess command-line concatenation in wpopenv() lets a srcip containing spaces add further arguments, while disable-account.c can be abused to lock arbitrary system accounts. This issue is fixed in version 4.14.7.
