{"id":"DEBIAN-CVE-2026-19624","details":"A flaw was found in NetworkManager-l2tp. The plugin writes attacker-controlled VPN connection properties (vpn.data and vpn.secrets values) unescaped into a generated ipsec.conf file that pluto loads as root. A local unprivileged user can create and activate their own L2TP VPN profile containing a newline-injected leftupdown directive; pluto executes that command as root when the IKE security association is established, resulting in local privilege escalation. This is the same bug class as CVE-2018-10900 (NetworkManager-vpnc).","modified":"2026-09-19T22:47:40.493721812Z","published":"2026-09-14T20:16:43.593Z","upstream":["CVE-2026-19624"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-19624"}],"affected":[{"package":{"name":"network-manager-l2tp","ecosystem":"Debian:12","purl":"pkg:deb/debian/network-manager-l2tp?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.20.10-1","1.20.12-1","1.20.16-1","1.20.20-1","1.20.20-2","1.20.8-1","1.52.0-1","1.52.0-2","1.52.2-1","1.52.4-1","1.52.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-19624.json"}},{"package":{"name":"network-manager-l2tp","ecosystem":"Debian:13","purl":"pkg:deb/debian/network-manager-l2tp?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.20.20-2+deb13u1"}]}],"versions":["1.20.20-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-19624.json"}},{"package":{"name":"network-manager-l2tp","ecosystem":"Debian:14","purl":"pkg:deb/debian/network-manager-l2tp?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.52.6-1"}]}],"versions":["1.20.20-2","1.52.0-1","1.52.0-2","1.52.2-1","1.52.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-19624.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
