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