Title
Tautulli vulnerable to Unauthenticated Path Traversal in `real_pms_image_proxy`
Summary
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. The `real_pms_image_proxy` endpoint in Tautulli v2.15.3 and prior is vulnerable to path traversal, allowing unauthenticated attackers to read arbitrary files from the application server's filesystem. The `real_pms_image_proxy` is used to fetch an image directly from the backing Plex Media Server. The image to be fetched is specified through an `img` URL parameter, which can either be a URL or a file path. There is some validation ensuring that `img` begins with the prefix `interfaces/default/images` in order to be served from the local filesystem. However this can be bypassed by passing an `img` parameter which begins with a valid prefix, and then adjoining path traversal characters in order to reach files outside of intended directories. An attacker can exfiltrate files on the application file system, including the `tautulli.db` SQLite database containing active JWT tokens, as well as the `config.ini` file which contains the hashed admin password, the JWT token secret, and the Plex Media Server token and connection details. If the password is cracked, or if a valid JWT token is present in the database, an unauthenticated attacker can escalate their privileges to obtain administrative control over the application. Version 2.16.0 contains a fix for the issue.

El punto final \u0027real_pms_image_proxy\u0027 en Tautulli v2.15.3 y anteriores es vulnerable a salto de ruta, permitiendo a atacantes no autenticados leer archivos arbitrarios del sistema de archivos del servidor de aplicaciones. El \u0027real_pms_image_proxy\u0027 se utiliza para obtener una imagen directamente del Plex Media Server de respaldo. La imagen a obtener se especifica a trav\u00e9s de un par\u00e1metro URL \u0027img\u0027, que puede ser una URL o una ruta de archivo.

Sin embargo, esto puede ser eludido pasando un par\u00e1metro \u0027img\u0027 que comienza con un prefijo v\u00e1lido, y luego adjuntando caracteres de salto de ruta para alcanzar archivos fuera de los directorios previstos.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
