A non-feature complete authentication mechanism exists in the production application allowing an attacker to bypass all authentication checks if LDAP authentication is selected.An unauthenticated attacker can leverage this vulnerability to log in to the CypberPower PowerPanel Enterprise as an administrator by selecting LDAP authentication from a hidden HTML combo box. Successful exploitation of this vulnerability also requires the attacker to know at least one username on the device, but any password will authenticate successfully.
