7.5 highCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NCVE-2021-45458
High (7.5) in apache kylin. EPSS 2.1% chance of exploitation in the next 30 days. Fixed in org.apache.kylin:kylin 3.1.3, 4.0.1.
Apache Kylin provides encryption classes PasswordPlaceholderConfigurer to help users encrypt their passwords. In the encryption algorithm used by this encryption class, the cipher is initialized with a hardcoded key and IV. If users use class PasswordPlaceholderConfigurer to encrypt their password and configure it into kylin's configuration file, there is a risk that the password may be decrypted. This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions; Apache Kylin 4 version 4.0.0 and prior versions.
