phpMyAdmin: Security bypass

phpMyAdmin: Security bypass A vulnerability in phpMyAdmin might allow remote attackers to bypass authentication. phpmyadmin 2017-07-08 2017-08-06: 2 614522 remote 4.0.10.20 4.7.0 4.0.10.20 4.7.0

phpMyAdmin is a web-based management tool for MySQL databases.

A vulnerability was discovered where the restrictions caused by “$cfg[‘Servers’][$i][‘AllowNoPassword’] = false” are bypassed under certain PHP versions. This can lead compromised user accounts, who have no passwords set, even if the administrator has set “$cfg[‘Servers’][$i][‘AllowNoPassword’]” to false (which is the default).

This behavior depends on the PHP version used (it seems PHP 5 is affected, while PHP 7.0 is not).

A remote attacker, who only needs to know the username, could bypass security restrictions and access phpMyAdmin.

Set a password for all users.

All phpMyAdmin 4.0.x users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose
      ">=dev-db/phpmyadmin-4.0.10.20:4.0.10.20"

All other phpMyAdmin users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-db/phpmyadmin-4.7.0:4.7.0"
