      "value": "In open-webui version 0.3.8, the endpoint `/models/upload` is vulnerable to arbitrary file write due to improper handling of user-supplied filenames. The vulnerability arises from the usage of `file_path = f\"{UPLOAD_DIR}/{file.filename}\"` without proper input validation or sanitization. An attacker can exploit this by manipulating the `file.filename` parameter to include directory traversal sequences, causing the resulting `file_path` to escape the intended `UPLOAD_DIR` and potentially overwrite arbitrary files on the system. This can lead to unauthorized modifications of system binaries, configuration files, or sensitive data, potentially enabling remote command execution."

La vulnerabilidad surge del uso de `file_path = f\"{UPLOAD_DIR}/{file.filename}\"` sin la validaci\u00f3n ni la depuraci\u00f3n adecuada de la entrada. Un atacante puede explotar esto manipulando el par\u00e1metro `file.filename` para incluir secuencias de navegaci\u00f3n de directorio, lo que provoca que el `file_path` resultante escape del `UPLOAD_DIR` previsto y, potencialmente, sobrescriba archivos arbitrarios en el sistema. Esto puede provocar modificaciones no autorizadas de binarios del sistema, archivos de configuraci\u00f3n o datos confidenciales, lo que podr\u00eda permitir la ejecuci\u00f3n remota de comandos."
