Detailsinfo

A vulnerability, which was classified as problematic, has been found in Tautulli up to 2.15.x. Affected by this issue is some unknown processing of the file /image of the component API Endpoint. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-23. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. Impacted is confidentiality. CVE summarizes:

Tautulli is a Python based monitoring and tracking tool for Plex Media Server. The `/image` API endpoint in Tautulli v2.15.3 and earlier is vulnerable to path traversal, allowing unauthenticated attackers to read arbitrary files from the application server's filesystem. In Tautulli, the `/image` API endpoint is used to serve static images from the application's data directory to users. This endpoint can be accessed without authentication, and its intended purpose is for server background images and icons within the user interface. Attackers can exfiltrate files from 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.
