FKIE_CVE-2025-48384

Vulnerability from fkie_nvd - Published: 2025-07-08 19:15 - Updated: 2025-11-06 14:52
Severity ?
8.0 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H
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 reading a config value, Git strips any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR are not quoted, causing the CR to be lost when the config is later read. When initializing a submodule, if the submodule path contains a trailing CR, the altered path is read resulting in the submodule being checked out to an incorrect location. If a symlink exists that points the altered path to the submodule hooks directory, and the submodule contains an executable post-checkout hook, the script may be unintentionally executed after checkout. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1.

Al leer un valor de configuraci\u00f3n, Git elimina cualquier retorno de carro y avance de l\u00ednea (CRLF) final. Al escribir una entrada de configuraci\u00f3n, los valores con un CR final no se entrecomillan, lo que provoca que el CR se pierda al leer la configuraci\u00f3n posteriormente. Al inicializar un subm\u00f3dulo, si la ruta del subm\u00f3dulo contiene un CR final, se lee la ruta modificada, lo que provoca que el subm\u00f3dulo se extraiga a una ubicaci\u00f3n incorrecta. Si existe un enlace simb\u00f3lico que apunta la ruta modificada al directorio de ganchos del subm\u00f3dulo, y este contiene un gancho ejecutable posterior a la extracci\u00f3n, el script podr\u00eda ejecutarse accidentalmente despu\u00e9s de la extracci\u00f3n.
