Descriptions
A "javascript:" url loaded by a malicious page can obfuscate its location by blanking the URL displayed in the addressbar, allowing for an attacker to spoof an existing page without the malicious page's address being displayed correctly. This vulnerability affects Firefox < 52.
Una URL "javascript:" cargada por una página maliciosa puede ofuscar su ubicación dejando en blanco la URL mostrada en la barra de direcciones, lo que permite que un atacante suplante una página existente sin que la dirección maliciosa de la página se muestre correctamente. La vulnerabilidad afecta a Firefox en versiones anteriores a la 52.
