  1. CVE-2026-58393 5.9 Moyenne

    opnsense core

    OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.11, the OpenVPN Client Specific Override common_name field accepts path traversal sequences and openvpn_csc_conf_write() concatenates the value into /var/etc/openvpn-csc/<vpnid>/<common_name> without normalization or a basename check. The affected event handlers are client_connect.php and user_pass_verify.php. An authenticated user with Client Specific Override privileges can store the traversal value, and a matching OpenVPN client-connect or authentication event causes a generated CSO file to be written outside the intended directory. The file content is generated OpenVPN configuration rather than arbitrary bytes, and practical exploitation requires the attacker to cause a matching common name or username to be processed. This issue is fixed in version 26.1.11.

    OpenVPN ovpn-dco-win

    Improper synchronization in the OpenVPN ovpn-dco-win for Windows versions 0.6.5 through 1.3.5 and 2.4.0 through 2.8.7 allows local attackers to trigger a deadlock via a crafted write to the ovpn-dco device, causing the host to become unresponsive.
