SV-16930r1_rule Firefox is configured to allow JavaScript to change the status bar text.

Vulnerability discussion

JavaScript can make changes to the browser’s appearance. This activity can help disguise an attack taking place in a minimized background window. Webpage authors can disable many features of a popup window that they open. Setting these preferences to true will override the author's settings and ensure that the feature is enabled and present in any popup window. This setting prevents the status bar from being hidden.

Check content

In About:Config, verify that the preference “dom.disable_window_open_feature.status" is set and locked to “true”. Criteria: If the parameter is set incorrectly, then this is a finding. If the setting is not locked, then this is a finding.

Fix text

Ensure the preference "dom.disable_window_open_feature.status" is set and locked to the value of “true”.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
