Functions

func DetectMongoDB

func DetectMongoDB(conn net.Conn, timeout time.Duration) (mongoDBMetadata, bool, error)

DetectMongoDB performs MongoDB fingerprinting using a layered fallback approach. It attempts detection using both OP_QUERY (universal) and OP_MSG (MongoDB 3.6+) protocols to ensure compatibility across all MongoDB versions from ancient to unreleased.

Detection Strategy:

1. DETECTION PHASE: Use hello/isMaster commands to detect MongoDB and extract metadata - PRIMARY PATH (OP_QUERY): Try OP_QUERY + "hello", then OP_QUERY + "isMaster" Works on ALL MongoDB versions, including 5.1+ (handshake exception) Extracts: version, maxWireVersion, minWireVersion, serverType - SECONDARY PATH (OP_MSG): Try OP_MSG + "hello", then OP_MSG + "isMaster" Works on MongoDB 3.6+ only Extracts: version, maxWireVersion, minWireVersion, serverType
2. ENRICHMENT PHASE: If version not found in hello/isMaster, try buildInfo - Attempts buildInfo with both OP_QUERY and OP_MSG protocols - If buildInfo fails (e.g., requires auth), still returns MongoDB detection

Parameters:

• conn: Network connection to the MongoDB server
• timeout: Timeout duration for network operations

Returns:

• mongoDBMetadata: Enriched metadata (version, wire versions, server type)
• bool: true if this appears to be MongoDB
• error: Error details if detection failed
