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是美国Wazuh公司开源的一款安全检测与威胁分析平台。 Wazuh 4.2.0至4.14.6版本存在命令注入漏洞，该漏洞源于多个active response脚本未验证srcip和dstuser等警报字段的格式，将其传递给以root运行的特权系统命令，可能导致参数注入，攻击者可通过注入特制日志事件来添加额外命令参数或锁定任意系统账户。

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.
