Summary

Pathling Server before version 2.0.0 has a path traversal vulnerability in the `/$result` endpoint. A caller who can obtain a valid async export job ID can supply `file` parameter values with path traversal sequences, allowing reading files outside the job's directory, including warehouse data.

Risk Assessment

An attacker can access sensitive data stored in the warehouse, compromising confidentiality.

Recommendation

Upgrade Pathling Server to version 2.0.0, which normalizes paths and rejects requests escaping the job directory. As interim mitigation, disable export operations or restrict access to trusted callers.

Original NVD description (English source)

Pathling is a set of tools that make it easier to use FHIR and clinical terminology within health data analytics. Prior to version 2.0.0 of Pathling Server, Pathling's `/$result` endpoint allows a caller who can obtain any valid async export job ID to supply `file` parameter values containing path traversal sequences. The handler verifies only the supplied `job` and never normalises or confines the requested `file` path to that job's `jobs/<jobId>` directory before opening it as a filesystem resource. Because async export scratch space lives under the same warehouse database root as persisted resource tables, an attacker can use their own export job to read other files from the warehouse. This is fixed in Pathling Server 2.0.0. The `$result` handler now resolves and canonicalizes the requested file path and rejects any request that escapes the job's `jobs/<jobId>` directory. As an interim mitigation, disable the async export operations (`pathling.operations.exportEnabled`, `patientExportEnabled`, `groupExportEnabled`, `bulkSubmitEnabled`) or enable authentication and restrict export capability to trusted callers.
