Descriptions

Telegram Desktop before 1.5.12 on Windows, and the Telegram applications for Android, iOS, and Linux, is vulnerable to an IDN homograph attack when displaying messages containing URLs. This occurs because the application produces a clickable link even if (for example) Latin and Cyrillic characters exist in the same domain name, and the available font has an identical representation of characters from different alphabets.

Telegram Desktop, en versiones anteriores a la 1.5.12 en Windows, y las aplicaciones de Telegram para Android, iOS y Linux son vulnerables a un ataque de homógrafo IDN al mostrar mensajes que contienen URL. Esto ocurre porque la aplicación produce un enlace sobre el que se puede hacer clic aunque, por ejemplo, existan caracteres latinos y cirílicos en el mismo nombre de dominio, y la fuente disponible tiene una representación idéntica de caracteres procedentes de distintos alfabetos.
