When user clicks on a specially crafted a malicious URL, if user does not carefully pay attention to url, user may be tricked to think content may be coming from a valid domain, while it comes from another. This is performed by using a very long username part of the url so that user cannot see the domain name. A remote attacker can leverage this to perform url address bar spoofing attack. The fix is, browser no longer shows the user name part in address bar."}, {"lang": "es", "value": "Se ha detectado una vulnerabilidad de suplantaci\u00f3n de la Barra de Direcciones URL en Safe Browser para iOS. Cuando el usuario hace clic en una URL maliciosa especialmente dise\u00f1ada, si el usuario no presta atenci\u00f3n a la url, puede ser enga\u00f1ado para pensar que el contenido puede venir de un dominio v\u00e1lido, mientras que viene de otro. Esto se lleva a cabo al usar una parte del nombre de usuario muy larga en la url para que el usuario no pueda visualizar el nombre del dominio. Un atacante remoto puede aprovechar esto para llevar a cabo un ataque de suplantaci\u00f3n de la barra de direcciones url. La correcci\u00f3n es que el navegador ya no muestra la parte del nombre de usuario en la barra de direcciones"}], "lastModified": "2022-01-03T13:17:29.717", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:f-secure:safe:*:*:*:*:*:iphone_os:*:*", "vulnerable": true, "matchCriteriaId": "89EFB376-80FA-4576-9560-EFFC8BA88A42", "versionEndExcluding": "18.3"}], "operator": "OR"}]}], "sourceIdentifier": "cve-notifications-us@f-secure.com"}
