Versions prior to 16.6.6 and 17.0.2 have an arbitrary file write vulnerability in OpenProject\u2019s repository diff download endpoint (`/projects/:project_id/repository/diff.diff`) when rendering a single revision via git show. By supplying a specially crafted rev value (for example, `rev=--output=/tmp/poc.txt)`, an attacker can inject git show command-line options. When OpenProject executes the SCM command, Git interprets the attacker-controlled rev as an option and writes the output to an attacker-chosen path. As a result, any user with the `:browse_repository` permission on the project can create or overwrite arbitrary files that the OpenProject process user is permitted to write. The written contents consist of git show output (commit metadata and patch), but overwriting application or configuration files still leads to data loss and denial of service, impacting integrity and availability. The issue has been fixed in OpenProject 17.0.2 and 16.6.6."}, {"lang": "es", "value": "OpenProject es un software de gesti\u00f3n de proyectos de c\u00f3digo abierto y basado en la web. Las versiones anteriores a la 16.6.6 y 17.0.2 tienen una vulnerabilidad de escritura de archivos arbitraria en el endpoint de descarga de diferencias del repositorio de OpenProject (`/projects/:project_id/repository/diff.diff`) al renderizar una \u00fanica revisi\u00f3n a trav\u00e9s de git show. Al proporcionar un valor de rev especialmente dise\u00f1ado (por ejemplo, `rev=--output=/tmp/poc.txt)`), un atacante puede inyectar opciones de l\u00ednea de comandos de git show. Cuando OpenProject ejecuta el comando SCM, Git interpreta el rev controlado por el atacante como una opci\u00f3n y escribe la salida en una ruta elegida por el atacante. Como resultado, cualquier usuario con el permiso :browse_repository en el proyecto puede crear o sobrescribir archivos arbitrarios que el usuario del proceso de OpenProject tiene permiso para escribir. El contenido escrito consiste en la salida de git show (metadatos de commit y parche), pero sobrescribir archivos de aplicaci\u00f3n o configuraci\u00f3n a\u00fan conduce a la p\u00e9rdida de datos y a la denegaci\u00f3n de servicio, afectando la integridad y la disponibilidad.
