GSD-2021-36774

Vulnerability from gsd - Updated: 2023-12-13 01:23
Details
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.
