CVE-2026-111216— Netgate pfSense CE through 2.9.0 OS Command Injection via Gateway Monitor IP

Quick assessment

Affected

Netgate pfSense CE

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.

Netgate pfSense CE 2.9.0 及更早版本中存在操作系统命令注入漏洞。拥有网关编辑权限的已认证用户可通过向 IPv6 链路本地地址的区域索引（zone index）注入 shell 元字符，以 root 权限执行任意命令。攻击者可以将网关的“监控 IP”（Monitor IP）设置为一个包含恶意载荷且未经验证的区域字符串。当启用监控功能时，函数会将该区域字符串未经转义地传递给 shell 命令，从而导致命令注入。

Vulnerability Description

Netgate pfSense CE through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with gateway edit privileges to execute commands as root by injecting shell metacharacters into an IPv6 link-local zone index. Attackers can set a gateway Monitor IP whose unvalidated zone carries a payload, which start_dpinger() passes unescaped to the dpinger shell command when monitoring is applied.
