CyberRota Analysis

AI-Generated

Tautulli versions prior to 2.17.2 are vulnerable to a directory traversal attack via the import_config handler and the database_file branch, allowing an attacker with API access to manipulate file uploads outside the intended CACHE_DIR. This can lead to configuration tampering, service disruption, or potential code execution. Administrators using Tautulli should prioritize upgrading to version 2.17.2 to mitigate these risks.

Original NVD Description

Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to 2.17.2, the import_config handler and the database_file branch of import_database in plexpy/webserve.py join the attacker-controlled config_file.filename or database_file.filename directly to CACHE_DIR without basename reduction or a containment check. An administrator or caller with the instance API key can submit a multipart filename containing parent-directory segments, causing the upload to be created or overwritten outside CACHE_DIR before file-content validation runs. The write is limited to paths permitted to the Tautulli process, but it can enable configuration tampering, service disruption, or code execution. This issue is fixed in version 2.17.2.
