CVE-2021-36774: Apache Kylin

Medium severity, CVSS 6.5. EPSS: 1.9% chance of exploitation in the next 30 days.

Apache Kylin allows users to read data from other database systems using JDBC. The MySQL JDBC driver supports certain properties, which, if left unmitigated, can allow an attacker to execute arbitrary code from a hacker-controlled malicious MySQL server within Kylin server processes. This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions.

Affected products

• Apache Kylin: from 2.0.0, up to and including 2.6.6; from 3.0.0, up to and including 3.1.2
