Use Narrow Permissions + +```typescript +// ✓ GOOD: Client gets auth only for specific blob +const auth = await blobService.createBlobWriteAuthorizationHeader({ + containerName: 'uploads', + blobName: `user-${userId}/avatar.jpg`, // Specific to this user + contentLength: fileSize, + contentType, +}); + +// ✗ BAD: Don't give client a generic SAS token for entire container +// (they could upload arbitrary files) +``` + +### 2. Validate on Server Before Signing + +```typescript +// ✓ GOOD: Server validates before generating auth +async function requestUploadAuth(req: Request) { + const userId = req.user.id; // Authenticated + const { fileSize, contentType } = req.body; + + // Validate + if (fileSize > 5 * 1024 * 1024) throw new Error('Max 5MB'); + if (!allowedTypes.includes(contentType)) throw new Error('Invalid type'); + + // Only then sign + const auth = await blobService.createBlobWriteAuthorizationHeader({ + containerName: 'uploads', + blobName: `${userId}.jpg`, + contentLength: fileSize, + contentType, + }); + + return auth; +} +``` + +### 3. Use Short-Lived Tokens + +```typescript +// Consider adding expiration to the header +// (separate from blob storage, via application logic) +const auth = await blobService.createBlobWriteAuthorizationHeader(...); +const expiresAt = Date.now() + 15 * 60 * 1000; // 15 minutes + +// Client must upload within 15 minutes +return { auth, expiresAt }; +``` + +### 4. Verify in Logs + +```typescript +// After client uploads, verify in Azure Storage logs +// that the operation succeeded (201 Created) +// If you see 403 errors, it indicates tampering attempt + +// Check Azure Monitor -> Log Analytics +// Query: StorageAccount_Events where OperationName == "PutBlob" +``` + +## Limitations & Caveats + +### 1. No Expiration Built-In + +The signature itself doesn't expire. You must: +- Track server-side: "This header is valid until X time" +- Or: Client submits header; server checks if still within valid window + +### 2. Date Header Replay + +If client captures an auth header today and tries to use it tomorrow, it might fail if your validation checks x-ms-date staleness. + +**Mitigation**: Use short TTL for auth headers (15 minutes recommended). + +### 3. Account Key Compromise + +If the storage account key is leaked, attacker can forge any signature. + +**Mitigation**: +- Rotate keys regularly (Azure can do this automatically) +- Use managed identity for backend ops (no keys in code) +- Keep connection string in secure storage (Key Vault) + +## Testing Metadata-Locking + +Cellix includes comprehensive tests verifying metadata-locking: + +```typescript +// Run tests +pnpm --filter @cellix/service-blob-storage run test + +// Look for tests like: +// ✓ auth header for one blob cannot be reused for a different blob +// ✓ auth header locks in content-length metadata +// ✓ auth header locks in content-type metadata +// ✓ auth header locks in blob metadata +// ✓ auth header locks in HTTP method +``` + +All tests pass against both Azurite (local) and Azure Storage (production). + +## Related Documentation + +- [Client Uploads Implementation](./client-uploads-with-auth-headers) +- [Authentication Strategies](./authentication-strategies) +- [Official Azure Documentation](https://learn.microsoft.com/en-us/rest/api/storageservices/authorize-with-shared-key) diff --git a/apps/docs/docs/technical-overview/blob-storage/05-troubleshooting.md b/apps/docs/docs/technical-overview/blob-storage/05-troubleshooting.md new file mode 100644 index 000000000..b42a36b63 --- /dev/null +++ b/apps/docs/docs/technical-overview/blob-storage/05-troubleshooting.md @@ -0,0 +1,374 @@ +--- +sidebar_position: 5 +title: "Troubleshooting" +description: "Common issues, configuration errors, and solutions" +--- + +# Troubleshooting Blob Storage + +## Configuration Errors + +### Error: "Either connectionString or accountName must be provided" + +**Cause**: `ServiceBlobStorage` constructor called without both options. + +**Solution**: +```typescript +// ✗ WRONG +const blobService = new ServiceBlobStorage({});
