To avoid potential exposure of data, the autocomplete attribute is now turned off for many fields containing sensitive information, such as a user's password for logging into Zabbix, pre-shared keys (PSK), macro values, usernames and passwords used for data collection by various items and hosts, SNMPv3 authentication and privacy passphrases, passwords for media types; SSL key password and HTTP proxy fields used in web scenarios and HTTP items; usernames, passwords and key passphrases in remote commands. This setting shall prevent most browsers from using autocompletion in the affected fields.
To make sure an attacker may not guess valid user names because temporary account blocking after consecutive failed login attempts is only applied to existing user names, the account blocking is now also enforced if non-existing user names are used.
To further obscure the possibility of such attacks, a unified generic message is now displayed for all problems related to incorrect login:
Incorrect user name or password or account is temporarily blocked.
