Apache Kylin is an open-source Analytical Big Data engine that provides SQL interface and OLAP on top of Hadoop/Presto. It is designed to support large-scale data handling with high performance. Kylin makes querying data simpler and faster by using pre-aggregation technology for speeding up query times. It is used mainly for Business Intelligence and Analytics, providing a powerful, efficient, and flexible tool for analyzing large data sets.
However, the CVE-2020-13937 vulnerability has been detected in the software. This vulnerability has exposed Kylin's configuration information without any authentication, making it dangerous as sensitive information can be disclosed to everyone. It is caused by the Kylin restful API, which does not apply any authentication, allowing an attacker to access sensitive data without any prior login.
If the CVE-2020-13937 vulnerability is exploited, it can lead to serious consequences such as leaking confidential data, network infiltration, unauthorized access, and other cyberattacks. Cybercriminals can easily access personal data, bank account details, and other sensitive information that they can exploit for their benefit. With the vulnerability, any attacker that touches Kylin software can extract confidential information without any restrictions.
