CVE-2018-18380
Estado: ModificadaMedia (5.4)—
A Session Fixation issue was discovered in Bigtree before 4.2.24. admin.php accepts a user-provided PHP session ID instead of regenerating a new one after a user has logged in to the application. The Session Fixation could allow an attacker to hijack an admin session.
