XSS through FPD

PMASA-2016-24

Announcement-ID: PMASA-2016-24

Date: 2016-06-23

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.
