📝 Walkthrough

Walkthrough

The PR adds diagnostic-document push, central S3 ingestion, and download-URL endpoints. It adds configuration, repository updates, and AWS S3 clients for these flows. The Nikshay export query now reads HIV status from the latest eligible tb_screening row.

Changes

Diagnostic Document Synchronization

Layer / File(s)	Summary
Configure and push local documents pom.xml, src/main/environment/common_*.properties, src/main/java/com/iemr/mmu/config/S3ClientConfig.java, src/main/java/com/iemr/mmu/service/dataSyncLayerCentral/DiagnosticDocumentRepository.java, src/main/java/com/iemr/mmu/utils/CryptoUtil.java, src/main/java/com/iemr/mmu/service/dataSyncLayerCentral/DiagnosticDocumentPushServiceImpl.java, src/main/java/com/iemr/mmu/controller/dataSyncActivity/StartSyncActivity.java	Adds AWS S3 dependencies, settings, client beans, and local document repository operations. The push endpoint sends decrypted documents in batches and records success or failure from central acknowledgements.
Receive and store documents centrally src/main/java/com/iemr/mmu/controller/dataSyncLayerCentral/MMUDataSyncVanToServer.java, src/main/java/com/iemr/mmu/service/dataSyncLayerCentral/DiagnosticDocumentIngestService.java	Adds a central POST endpoint and per-document processing. The service validates required fields and any supplied SHA-256 hash, stores valid content in S3 with AES-256 server-side encryption, and returns acknowledgements.
Find documents and return download URLs src/main/java/com/iemr/mmu/service/dataSyncLayerCentral/DiagnosticDocumentRepository.java, src/main/java/com/iemr/mmu/service/dataSyncLayerCentral/DiagnosticDocumentFetchService.java, src/main/java/com/iemr/mmu/controller/dataSyncActivity/StartSyncActivity.java	Adds lookup of the latest successfully pushed document and a 15-minute presigned S3 URL. The download endpoint returns the URL and document metadata when a match exists.

Nikshay Export HIV Status

Layer / File(s)	Summary
Update HIV-status source src/main/java/com/iemr/mmu/repo/stoptb/NikshayExportRepository.java	The HIV-status subquery now selects the latest qualifying tb_screening row, including rows with deleted set to 0 or NULL.

Merge Risk: 🟠 High · up to 98e3c

The new central document-upload endpoint accepts requests without verified authentication and stores their content in S3. Patient diagnostic documents are protected by an encryption key committed in the repository. Crafted filenames or types can also overwrite other patients' stored documents. These issues should be fixed before merge.

Security Architecture Review

Security architecture risk: 🟠 High · up to 98e3c

The new central upload path does not enforce caller authentication or document ownership before writing to shared storage. Caller-selected object locations can affect other diagnostic documents, while a source-embedded decryption key and incomplete recovery controls further weaken confidentiality and integrity. Production network restrictions could reduce exposure, but were not established.

Retained concerns

• High · security · observed: The new central upload endpoint accepts an arbitrary Authorization header without authenticating its caller or validating document ownership. Caller-selected content and namespace fields reach privileged S3 writes, expanding the application boundary to unauthorized creation or replacement of diagnostic objects.
• Medium · security · observed: The added decryption helper embeds a fixed AES key in source and uses it to decrypt local diagnostic files. Possession of the application source or binary plus matching encrypted files supplies offline decryption authority without environment-specific secret separation. The underlying encryption producer and prior exposure of this key were not established.
• Medium · security · inferred: The new storage key omits document identity and content version, while downloads trust the recorded key. Distinct documents sharing the same namespace tuple can replace one another's served content. The local producer also assigns one request-supplied village ID to every pending row rather than deriving village ownership per document. Filename uniqueness and a single-village database invariant were not evidenced.
• Medium · reliability · inferred: S3 writes and local status updates are separate, uncoordinated transitions. A lost acknowledgement can leave an uploaded object marked failed locally; overlapping push runs can let a delayed failure clear a previously successful object's recorded path. The examined workflow has no reservation, conditional status transition, or reconciliation step, weakening containment and recovery of sensitive-document state.

Security review details

Security Blast Radius

• inferred — A caller able to reach central ingestion needs only a syntactically present Authorization header to submit writes at the application boundary. Attackable scope spans request-constructible village/beneficiary object namespaces in the configured bucket, subject to actual IAM and bucket policy. The path does not itself establish arbitrary-bucket access or direct document reading.

Security Findings and Attack Paths

• observed — The retained authorization-bypass finding is supported by the resolved route and source trace: request body to ingestion, caller-selected object key/content, then privileged PutObject. Hash validation verifies only an optional caller-supplied digest; it does not authenticate the document's origin.
• observed — The retained sensitive-data finding identifies a literal key used directly for AES decryption. The new transfer producer invokes that helper on stored files, linking embedded key possession to diagnostic-file confidentiality rather than to an externally exposed decryption API.

Trust Boundaries and Controls

• observed — Local push and URL issuance inherit DATASYNC/DATA_SYNC method authorization. Central ingestion does not inherit that protection and does not bind supplied village, beneficiary, or document identifiers to a principal. The protected producer is therefore not a control over direct central callers.

Resilience and Maintainability Implications

• inferred — Deterministic keys limit duplicate-object creation for unchanged retries but do not preserve immutable document identity. Unconditional P/F updates also allow competing completions to regress state, so retry behavior can alter served content or erase the local association to an existing object.

Hardening Proposals

• proposed — Authenticate the central producer and authorize each document against authoritative ownership before upload. Derive allowed object namespaces from that identity, constrain write permissions, and enforce bounded payload size and item count at the consumer.
• proposed — Use document/version-bound object identity, conditional monotonic status transitions, and reconciliation for uncertain upload outcomes. Replace embedded decryption authority with separately managed, rotatable keys using a compatibility plan for existing encrypted files.

- Around line 85-101: Add a role authorization check to
diagnosticDocumentsFromVan so only users with the data-sync role can invoke
ingestDocuments. Use the project’s accepted role names and ensure the check is
enforced despite the broad /dataSync/** permit rule.

- Around line 92-93: Validate orderType, documentType, and storedFileName before
constructing s3Key, rejecting values containing `/` or restricting them to safe
characters so request values cannot escape their intended S3 prefix.

- Line 23: Remove the hard-coded SECRET_KEY from CryptoUtil and load the AES key
from external configuration instead. Rotate the exposed key in this service and
FLW-API together, ensuring both use the coordinated replacement key.
