How to Fix CVE-2021-45458

To remediate this vulnerability, upgrade all affected Kylin dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.apache.kylin:kylin fixed: 3.1.3 
<dependency>
    <groupId>org.apache.kylin</groupId>
    <artifactId>kylin</artifactId>
    <version>3.1.3</version>
</dependency>
org.apache.kylin:kylin fixed: 4.0.1 
<dependency>
    <groupId>org.apache.kylin</groupId>
    <artifactId>kylin</artifactId>
    <version>4.0.1</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.apache.kylin

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-45458, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.kylin

Analyze the terminal output to locate any version of Kylin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.kylin command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-798: Use of Hard-coded Credentials, where the product contains hard-coded credentials, such as a password or cryptographic key. In Kylin, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
