{"id":"DEBIAN-CVE-2026-40082","details":"Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have missing session_regenerate_id() after login, leading to Session Fixation. session_regenerate_id() is NOT called after successful login. The login flow at auth_login.php:203-207 directly sets $_SESSION[SESS_USER_ID] without rotating the session ID. The session cookie configuration is otherwise good (httponly=true, samesite=Strict, secure=true for HTTPS at include/global.php:513-537), but these do not prevent session fixation via same-site vectors. This issue has been fixed in version 1.2.31.","modified":"2026-09-14T17:03:10.677842406Z","published":"2026-06-25T23:17:02.760Z","upstream":["CVE-2026-40082"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-40082"}],"affected":[{"package":{"name":"cacti","ecosystem":"Debian:12","purl":"pkg:deb/debian/cacti?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.24+ds1-1","1.2.24+ds1-1+deb12u1","1.2.24+ds1-1+deb12u2","1.2.24+ds1-1+deb12u3","1.2.24+ds1-1+deb12u4","1.2.24+ds1-1+deb12u5","1.2.25+ds1-1","1.2.25+ds1-2","1.2.26+ds1-1","1.2.27+ds1-1","1.2.27+ds1-2","1.2.28+ds1-1","1.2.28+ds1-2","1.2.28+ds1-3","1.2.28+ds1-4","1.2.30+ds1-1","1.2.30+ds1-2","1.2.30+ds1-3","1.2.31+ds1-1","1.2.31+ds1-2","1.2.31+ds1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40082.json"}},{"package":{"name":"cacti","ecosystem":"Debian:13","purl":"pkg:deb/debian/cacti?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.30+ds1-1","1.2.30+ds1-2","1.2.30+ds1-3","1.2.31+ds1-1","1.2.31+ds1-2","1.2.31+ds1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40082.json"}},{"package":{"name":"cacti","ecosystem":"Debian:14","purl":"pkg:deb/debian/cacti?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.31+ds1-1"}]}],"versions":["1.2.30+ds1-1","1.2.30+ds1-2","1.2.30+ds1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40082.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"}]}
