The FileManager in InfinitumIT DirectAdmin through v1.561 has XSS via CMD_FILE_MANAGER, CMD_SHOW_USER, and CMD_SHOW_RESELLER; an attacker can bypass the CSRF protection with this, and take over the administration panel.
JBMC DirectAdmin before 1.52, when the email_ftp_password_change setting is nonzero, allows remote attackers to obtain access or cause a denial of service (segfault) via an unspecified request.
Cross-site scripting (XSS) vulnerability in CMD_REDIRECT in DirectAdmin 1.33.6 and earlier allows remote attackers to inject arbitrary web script or HTML via the URI in a view=advanced request.
