Technical details
Session fixation vulnerability in loginlinkadmin.php, loginlinkfaculty.php, and loginlinkstudent.php components: the login handlers call session_start() but do not call session_regenerate_id(), so a pre-login session ID is promoted to an authenticated session. An attacker can fix a victim's PHPSESSID cookie, and after the victim logs in, the attacker's cookie becomes associated with the authenticated account. No fix is available; vendor did not respond to disclosure.
