GLSA-201707-03 : phpMyAdmin: Security bypass

Medium Nessus Plugin ID 101334


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-201707-03 (phpMyAdmin: Security bypass)

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).
Impact :

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

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-' 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'
