DescriptionGitHub Advisory

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.

AnalysisAI

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. An attacker with device management privileges could write files outside the intended media directory, potentially compromising system integrity.

Technical ContextAI

Classified as CWE-22 (Path Traversal). Affects Traccar. 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.

RemediationAI

Monitor vendor advisories for a patch. Validate and sanitize file path inputs. Use allowlists. Restrict network access to the affected service where possible.
