CVE-2026-111218— Netgate pfSense CE 2.7.0 through 2.9.0 OS Command Injection via Traffic Shaper Limiters

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 2.7.0 至 2.9.0 版本中存在一个操作系统命令注入漏洞。该漏洞允许拥有“流量整形限制器（Traffic Shaper Limiters）”权限的已认证用户，通过篡改限制器数量字段来执行具有 root 权限的命令。攻击者可在编辑限制器时提交一个恶意的隐藏“number”值，随后将其删除，从而使得 delete_queue() 函数将该未加引号的值通过 /bin/sh 以 root 身份传递给 dnctl，进而触发命令注入。

Vulnerability Title
Netgate pfSense CE 2.7.0 through 2.9.0 OS Command Injection via Traffic Shaper Limiters
Source: CVE Program / CVE List V5
Vulnerability Description
Netgate pfSense CE 2.7.0 through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with Traffic Shaper Limiters privileges to execute root commands by tampering with the limiter number field. Attackers can submit a malicious hidden 'number' value when editing a limiter, then delete it so delete_queue() passes the unquoted value to dnctl via /bin/sh as root.
