What is CVE-2019-15024?

The vulnerability allows an attacker with write access to ZooKeeper to run a malicious server that masquerades as a ClickHouse replica. This malicious server can register itself in ZooKeeper, leading other replicas to fetch data from it. Consequently, this enables the attacker to command the clickhouse-server to write data to arbitrary file system paths, potentially compromising the integrity of the server and the data it manages.
