Summary
XSS through FPD
Description
With a specially crafted request, it is possible to trigger an XSS attack through the example OpenID authentication script.
Severity
We do not consider this vulnerability to be secure due to the non-standard required PHP setting for html_errors.
Mitigation factor
The attack requires html_errors = Off in php.ini, so it can be mitigated by setting html_errors = On. As an alternative mitigation means, the ./examples/openid.php file can be removed.
Affected Versions
All 4.6.x versions (prior to 4.6.3), 4.4.x versions (prior to 4.4.15.7), and 4.0.x versions (prior to 4.0.10.16) are affected
Solution
Upgrade to phpMyAdmin 4.6.3, 4.4.15.7, or 4.0.10.16 or newer or apply patch listed below.
