CVE-2023-27296Network attack vector

Authenticated code execution via unsafe JDBC deserialization

Published Mar 27, 2023 · Updated Oct 23, 2024

Deserialization of untrusted data in Apache InLong 1.1.0 through 1.5.0 allows remote authenticated users to execute code via a MySQL JDBC URL. MySQLDataNode passes a user-supplied JDBC URL to the connector without first rejecting unsafe encoded connection parameters. The path requires an InLong account and access to Manager functionality that creates or tests a MySQL data node.
