Summary
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When Git asks for credentials via a terminal prompt (i.e. without using any credential helper), it prints out the host name for which the user is expected to provide a username and/or a password. At this stage, any URL-encoded parts have been decoded already, and are printed verbatim. This allows attackers to craft URLs that contain ANSI escape sequences that the terminal interpret to confuse users e.g. into providing passwords for trusted Git hosting sites when in fact they are then sent to untrusted sites that are under the attacker's control. This issue has been patch via commits `7725b81` and `c903985` which are included in release versions v2.48.1, v2.47.2, v2.46.3, v2.45.3, v2.44.3, v2.43.6, v2.42.4, v2.41.3, and v2.40.4. Users are advised to upgrade. Users unable to upgrade should avoid cloning from untrusted URLs, especially recursive clones.

      "value": "Git es un sistema de control de revisi\u00f3n distribuido, r\u00e1pido y escalable con un conjunto de comandos inusualmente rico que proporciona operaciones de alto nivel y acceso completo a los elementos internos. Cuando Git solicita credenciales a trav\u00e9s de un indicador de terminal (es decir, sin usar ning\u00fan asistente de credenciales), imprime el nombre de host para el que se espera que el usuario proporcione un nombre de usuario y/o una contrase\u00f1a. En esta etapa, todas las partes codificadas en URL ya han sido decodificadas y se imprimen textualmente. Esto permite a los atacantes crear URL que contienen secuencias de escape ANSI que la terminal interpreta para confundir a los usuarios, por ejemplo, para que proporcionen contrase\u00f1as para sitios de alojamiento de Git confiables cuando, de hecho, luego se env\u00edan a sitios que no son de confianza y que est\u00e1n bajo el control del atacante. Este problema se ha corregido mediante las confirmaciones `7725b81` y `c903985`, que est\u00e1n incluidas en las versiones de lanzamiento v2.48.1, v2.47.1, v2.46.3, v2.45.3, v2.44.3, v2.43.6, v2.42.4, v2.41.3 y v2.40.4. Se recomienda a los usuarios que actualicen la versi\u00f3n. Los usuarios que no puedan actualizar deben evitar la clonaci\u00f3n desde URL que no sean de confianza, especialmente clones recursivos."
