Vulnerability from fkie_nvd - Published: 2025-09-09 20:15 - Updated: 2026-10-19 17:10
Severity
9.1 (Critical) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
7.2 (High) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. In Tautulli v2.15.3 and earlier, an attacker with administrative access can use the `pms_image_proxy` endpoint to write arbitrary python scripts into the application filesystem. This leads to remote code execution when combined with the `Script` notification agent. If an attacker with administrative access changes the URL of the PMS to a server they control, they can then abuse the `pms_image_proxy` to obtain a file write into the application filesystem. This can be done by making a `pms_image_proxy` request with a URL in the `img` parameter and the desired file name in the `img_format` parameter. Tautulli then uses a hash of the desired metadata together with the `img_format` in order to construct a file path. Since the attacker controls `img_format` which occupies the end of the file path, and `img_format` is not sanitised, the attacker can then use path traversal characters to specify filename of their choosing. If the specified file does not exist, Tautaulli will then attempt to fetch the image from the configured PMS. Since the attacker controls the PMS, they can return arbitrary content in response to this request, which will then be written into the specified file. An attacker can write an arbitrary python script into a location on the application file system. The attacker can then make use of the built-in `Script` notification agent to run the local script, obtaining remote code execution on the application server. Users should upgrade to version 2.16.0 to receive a patch.

      "value": "Tautulli es una herramienta de monitoreo y seguimiento basada en Python para Plex Media Server. En Tautulli v2.15.3 y versiones anteriores, un atacante con acceso administrativo puede usar el endpoint \u0027pms_image_proxy\u0027 para escribir scripts Python arbitrarios en el sistema de archivos de la aplicaci\u00f3n. Esto lleva a la ejecuci\u00f3n remota de c\u00f3digo cuando se combina con el agente de notificaci\u00f3n \u0027Script\u0027. Si un atacante con acceso administrativo cambia la URL del PMS a un servidor que controla, puede entonces abusar del \u0027pms_image_proxy\u0027 para obtener una escritura de archivo en el sistema de archivos de la aplicaci\u00f3n. Esto se puede hacer realizando una solicitud \u0027pms_image_proxy\u0027 con una URL en el par\u00e1metro \u0027img\u0027 y el nombre de archivo deseado en el par\u00e1metro \u0027img_format\u0027. Tautulli luego usa un hash de los metadatos deseados junto con el \u0027img_format\u0027 para construir una ruta de archivo. Dado que el atacante controla \u0027img_format\u0027, que ocupa el final de la ruta de archivo, y \u0027img_format\u0027 no est\u00e1 sanitizado, el atacante puede entonces usar caracteres de salto de ruta para especificar el nombre de archivo de su elecci\u00f3n. Si el archivo especificado no existe, Tautulli intentar\u00e1 entonces obtener la imagen del PMS configurado. Dado que el atacante controla el PMS, puede devolver contenido arbitrario en respuesta a esta solicitud, que luego se escribir\u00e1 en el archivo especificado. Un atacante puede escribir un script Python arbitrario en una ubicaci\u00f3n del sistema de archivos de la aplicaci\u00f3n. El atacante puede entonces hacer uso del agente de notificaci\u00f3n \u0027Script\u0027 incorporado para ejecutar el script local, obteniendo ejecuci\u00f3n remota de c\u00f3digo en el servidor de aplicaciones. Los usuarios deben actualizar a la versi\u00f3n 2.16.0 para recibir un parche."
