CVE-2026-111221

pfSense CE 2.7.0 through 2.9.0 contains a command injection vulnerability in services_captiveportal_hasync.php that allows users with only the Captive Portal HA privilege to execute commands as root. Attackers can set backwardsyncip to a malicious XMLRPC server returning connected_users with shell metacharacters in ip or mac fields, which captiveportal_load_pfctl passes unescaped to a pfctl shell command.

pfSense CE 2.4.5 through 2.9.0 contains an OS command injection vulnerability that allows authenticated WebGUI users with Advanced Admin Access privilege to execute commands as root via Login Protection settings. Attackers can submit sshguard threshold, block time, or detection time values containing newlines or $(...) that are written unvalidated to sshguard.conf and sourced as root on restart.

pfSense CE through 2.9.0 contains an OS command injection vulnerability in the OpenVPN openvpn.connect_async.sh script that allows authenticated VPN users to execute commands as root via crafted usernames. Attackers authenticated through RADIUS or LDAP can use usernames containing single quotes and shell metacharacters to break out of the eval'd pfctl anchor name on connect or disconnect.

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.

Netgate pfSense CE through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with Virtual IP edit privileges to execute commands as root by storing an unvalidated CARP VHID. Attackers can supply a VHID containing shell metacharacters that executes via interface_ipalias_configure() ifconfig calls or get_carp_interface_status() when CARP status is rendered.

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.

Netgate pfSense CE through 2.9.0 contains an OS command injection vulnerability. An authenticated user with limited Wireless Edit or Interface Assignments privileges can supply a crafted wireless parent interface name (e.g. ath0;<cmd>), which is interpolated unescaped into an ifconfig shell command, allowing commands to be executed as root.

Netgate pfSense CE 2.7.0 through 2.9.0 contains an OS command injection vulnerability. An authenticated user with QinQ edit privilege can store an unvalidated parent interface name that is later interpolated into ifconfig shell commands, executing commands as root.

In pfSense CE, the suricata/suricata_ip_reputation.php file does not sanitize the iplist parameter against directory traversal sequences. This value is directly used in a file existence check, allowing an authenticated attacker to enumerate files on the server.

In pfSense CE, the file /usr/local/www/suricata/suricata_filecheck.php directly displays the value of the filehash parameter without sanitizing HTML-related characters/strings. This can result in reflected cross-site scripting (XSS) if the victim is authenticated.
