{"id":"DEBIAN-CVE-2017-18264","details":"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.","modified":"2026-09-01T16:04:23.321598552Z","published":"2018-05-01T17:29:00.237Z","upstream":["CVE-2017-18264"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2017-18264"}],"affected":[{"package":{"name":"phpmyadmin","ecosystem":"Debian:12","purl":"pkg:deb/debian/phpmyadmin?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4:4.6.6-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2017-18264.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Debian:13","purl":"pkg:deb/debian/phpmyadmin?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4:4.6.6-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2017-18264.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Debian:14","purl":"pkg:deb/debian/phpmyadmin?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4:4.6.6-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2017-18264.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
