CVE-2017-18264

Disclosure Date: May 01, 2018
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

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.
