Some Arabic and Indic vowel marker characters can be combined with Latin characters in a domain name to eclipse the non-Latin character with some font sets on the addressbar. The non-Latin character will not be visible to most viewers. This allows for domain spoofing attacks because these combined domain names do not display as punycode. This vulnerability affects Firefox < 57. Algunos caracteres marcas de vocales árabes e indios se pueden combinar con caracteres latinos en un nombre de dominio para eclipsar caracteres no latinos con algunas familias de fuentes en la barra de direcciones. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1370497 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-20: Improper Input Validation •

JavaScript can be injected into an exported bookmarks file by placing JavaScript code into user-supplied tags in saved bookmarks. If the resulting exported HTML file is later opened in a browser this JavaScript will be executed. This could be used in social engineering and self-cross-site-scripting (self-XSS) attacks if users were convinced to add malicious tags to bookmarks, export them, and then open the resulting file. This vulnerability affects Firefox < 57. Se puede inyectar código JavaScript en un archivo de marcadores exportado colocando código JavaScript en las etiquetas proporcionadas por el usuario en los marcadores guardados. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1366420 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2017-7839
Control characters prepended before "javascript:" URLs pasted in the addressbar can cause the leading characters to be ignored and the pasted JavaScript to be executed instead of being blocked. This could be used in social engineering and self-cross-site-scripting (self-XSS) attacks where users are convinced to copy and paste text into the addressbar. This vulnerability affects Firefox < 57. Caracteres de control precedidos de las URL "javascript:" pegadas en la barra de direcciones pueden hacer que se ignoren los caracteres principales y que se ejecute el código JavaScript pegado en lugar de bloquearse. Esto podría utilizarse en ataques de ingeniería social y auto-Cross-Site Scripting (self-XSS) donde se convence a los usuarios de que copien y peguen texto en la barra de direcciones. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1402896 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

A vulnerability where the security wrapper does not deny access to some exposed properties using the deprecated "_exposedProps_" mechanism on proxy objects. These properties should be explicitly unavailable to proxy objects. This vulnerability affects Firefox < 57. Una vulnerabilidad en la que el wrapper de seguridad no deniega el acceso a determinadas propiedades expuestas usando el mecanismo obsoleto "_exposedProps_" en los objetos proxy. Estas propiedades deberían no estar disponibles explícitamente para los objetos proxy. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1392026 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The combined, single character, version of the letter 'i' with any of the potential accents in unicode, such as acute or grave, can be spoofed in the addressbar by the dotless version of 'i' followed by the same accent as a second character with most font sets. This allows for domain spoofing attacks because these combined domain names do not display as punycode. This vulnerability affects Firefox < 57. El carácter único, combinado, versión de la letra "i"con uno de los acentos potenciales en unicode, como el agudo o el grave, se pueden suplantar en la barra de dirección mediante la versión sin puntos de "i" seguido del mismo acento como carácter secundarios con la mayoría de las familias de fuentes. Esto permite la realización de ataques de suplantación de dominios porque estos nombres de dominio combinados no se muestran como punycode. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1408782 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-20: Improper Input Validation •
