Weakness

The web application produces links to untrusted external sites outside of its sphere of control, but it does not properly prevent the external site from modifying security-critical properties of the window.opener object, such as the location property.

Affected Software

Potential Mitigations

• When creating a link to an external document using the tag with a defined target, for example “_blank” or a named frame, provide the rel attribute with a value “noopener noreferrer”.
• If opening the external document in a new window via javascript, then reset the opener by setting it equal to null.
• Do not use “_blank” targets. However, this can affect the usability of the application.
