A vulnerability classified as critical was found in phpMyAdmin up to 4.0.10.19/4.4.x/4.6.x/4.7.0 on PHP5 (Database Administration Software). Affected by this vulnerability is the function substr
of the file libraries/common.inc.php. The manipulation as part of a Argument leads to a credentials management vulnerability. The CWE definition for the vulnerability is CWE-255. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
An issue was discovered in libraries/common.inc.php in phpMyAdmin 4.0 before 4.0.10.20, 4.4.x, 4.6.x, and 4.7.0 prereleases. The restrictions caused by $cfg['Servers'][$i]['AllowNoPassword'] = false are bypassed under certain PHP versions (e.g., version 5). This can allow the login of users who have no password set even if the administrator has set $cfg['Servers'][$i]['AllowNoPassword'] to false (which is also the default). This occurs because some implementations of the PHP substr function return false when given '' as the first argument.
