Path Traversal Traccar

Description

Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users who can create or edit devices can set a device `uniqueId` to an absolute path. When uploading a device image, Traccar uses that `uniqueId` to build the filesystem path without enforcing that the resolved path stays under the media root. This allows writing files outside the media directory. As of time of publication, it is unclear whether a fix is available.

Analysis

Traccar GPS tracking system through version 6.11.1 allows authenticated users to conduct arbitrary file writes by setting device identifiers to absolute paths, which bypass path validation during image uploads. Public exploit code exists for this vulnerability, and no patch is currently available. …
