Name of the Vulnerable Software and Affected Versions Apache Kylin 2 versions 2.6.6 and prior Apache Kylin 3 versions 3.1.2 and prior Apache Kylin 4 versions 4.0.0 and prior

Description The issue is related to the use of Class.forName(...) which can load any class based on user input. This can potentially allow a remote attacker to impact the confidentiality, integrity, and availability of information. The vulnerability is associated with the application of external control input to select classes.

Recommendations For Apache Kylin 2 versions 2.6.6 and prior, update to a version later than 2.6.6. For Apache Kylin 3 versions 3.1.2 and prior, update to a version later than 3.1.2. For Apache Kylin 4 versions 4.0.0 and prior, update to a version later than 4.0.0. As a temporary workaround, consider restricting the use of the Class.forName(...) function to minimize the risk of exploitation.
