Description

The J-BusinessDirectory extension before 5.2.9 for Joomla! allows Reverse Tabnabbing. In some configurations the link to the business website can be entered by any user.

To reproduce the bug create a business with a website link that contains JavaScript to exploit the window.opener property (for example by setting window.opener.location).
