In versions of Onedev prior to 7.3.0 unauthenticated users can take over a OneDev instance if there is no properly configured reverse proxy. The /git-prereceive-callback endpoint is used by the pre-receive git hook on the server to check for branch protections during a push event. It is only intended to be accessed from localhost, but the check relies on the X-Forwarded-For header. Invoking this endpoint leads to the execution of one of various git commands. The environment variables of this command execution can be controlled via query parameters. This allows attackers to write to arbitrary files, which can in turn lead to the execution of arbitrary code. Such an attack would be very hard to detect, which increases the potential impact even more. Users are advised to upgrade. There are no known workarounds for this issue."}, {"lang": "es", "value": "Onedev es un servidor Git de c\u00f3digo abierto, auto-alojado con CI/CD y Kanban.
