Descriptions

WebExtensions with the appropriate permissions can attach content scripts to Mozilla sites such as accounts.firefox.com and listen to network traffic to the site through the "webRequest" API. For example, this allows for the interception of username and an encrypted password during login to Firefox Accounts. This issue does not expose synchronization traffic directly and is limited to the process of user login to the website and the data displayed to the user once logged in. This vulnerability affects Firefox < 60.

Las extensiones WebExtensions con los permisos apropiados pueden adjuntar scripts de contenido a sitios Mozilla como accounts.firefox.com y escuchar el tráfico de red en el sitio a través de la API "webRequest". Por ejemplo, esto permite la interceptación del nombre de usuario y una contraseña cifrada durante el inicio de sesión a las cuentas de Firefox. Este fallo no expone el tráfico de sincronización directamente y se limita al proceso de inicio de sesión del usuario en el sitio web y los datos mostrados al usuario una vez haya iniciado sesión. Esta vulnerabilidad afecta a las versiones anteriores a la 60 de Firefox.
