CVE-2024-45537: Apache Druid: Users can provide MySQL JDBC properties not on allow list

[Karan Kumar <karan () apache org>]

Severity: low

Affected versions:

- Apache Druid through 30.0.0

Description:

Apache Druid allows users with certain permissions to read data from other database systems using JDBC. This 
functionality allows trusted users to set up Druid lookups or run ingestion tasks. Druid also allows administrators to 
configure a list of allowed properties that users are able to provide for their JDBC connections. By default, this 
allowed properties list restricts users to TLS-related properties only. However, when configuration a MySQL JDBC 
connection, users can use a particularly-crafted JDBC connection string to provide properties that are not on this 
allow list.

Users without the permission to configure JDBC connections are not able to exploit this vulnerability.
CVE-2021-26919 describes a similar vulnerability which was partially addressed in Apache Druid 0.20.2.

This issue is fixed in Apache Druid 30.0.1.
