CVE-2020-5182

EUVD-2020-26429

03.02.2020, 17:15

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. If it doesn't contain rel="noopener" (or similar attributes such as noreferrer), the tabnabbing may occur. 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).
