Descriptions

The add-on installation feature in Mozilla Firefox before 40.0.3 and Firefox ESR 38.x before 38.2.1 allows remote attackers to bypass an intended user-confirmation requirement by constructing a crafted data: URL and triggering navigation to an arbitrary http: or https: URL at a certain early point in the installation process.

Vulnerabilidad en la funcionalidad de instalación de complemento en Mozilla Firefox en versiones anteriores a 40.0.3 y Firefox ESR 38.x en versiones anteriores a 38.2.1, permite a atacantes remotos eludir un requisito destinado a la confirmación de usuario por la construcción de un dato manipulado: URL y desencadenando la navegación a una URL http: o https: arbitraria en un cierto punto temprano del proceso de instalación.

A flaw was found in the way Firefox handled installation of add-ons. An attacker could use this flaw to bypass the add-on installation prompt, and trick the user into installing an add-on from a malicious source.
