CyberRota Analysis
AI-GeneratedPikiwiDB v3.5.7 is vulnerable due to an exposed internal protobuf replication server that lacks proper authentication for incoming requests, allowing unauthenticated remote attackers to connect and execute critical commands. This can lead to unauthorized access to full data snapshots, live write streams, and the ability to remove replica nodes, even if password protection is enabled. Organizations using this database version should prioritize patching this vulnerability to prevent potential data breaches and service disruptions.

Original NVD Description
PikiwiDB (Pika) v3.5.7 exposes an internal protobuf replication server on a port derived from the client port plus 2000 (e.g. 11221 when the default client port 9221 is used) that does not authenticate incoming requests. Although requirepass is intended to gate replication — a slave presents it as masterauth inside its MetaSync request — only the MetaSync handler (HandleMetaSyncRequest) validates it; the frame dispatcher (DealMessage) does not require a completed or attempted MetaSync before routing other message types to their handlers. As a result, an unauthenticated remote attacker can connect directly to the replication port and issue TrySync, DBSync, BinlogSync, and RemoveSlaveNode requests, obtaining the full-sync snapshot and live write stream and removing replica nodes, even when requirepass is configured.
