CVE-2026-111224 · Severity: high · CVSS 7.5 · Published 2026-10-15

pfSense CE is an open-source firewall that manages network access and VPN connections. A vulnerability in the OpenVPN connection script allows authenticated VPN users with crafted usernames to execute arbitrary commands with root privileges. Attackers using RADIUS or LDAP authentication can exploit this to take full control of the firewall and access all protected networks.

Technologies: [Netgate Pfsense Ce](https://junglewise.ai/threats/technologies/pfsense-ce). Vendors: [Netgate](https://junglewise.ai/threats/vendors/netgate).

## Technical details

An OS command injection vulnerability exists in the openvpn.connect_async.sh script where user-supplied usernames are passed unsafely to an eval'd pfctl anchor name. Authenticated VPN users (via RADIUS or LDAP) can inject shell metacharacters and single quotes in their username to break out of the eval context and execute arbitrary commands as root on connect or disconnect events. This requires prior VPN authentication but results in full system compromise.
