How to Fix CVE-2024-22533

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

com.ibeetl:beetl-core fixed: 3.15.13.RELEASE 
<dependency>
    <groupId>com.ibeetl</groupId>
    <artifactId>beetl-core</artifactId>
    <version>3.15.13.RELEASE</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=com.ibeetl

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-22533, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.ibeetl

Analyze the terminal output to locate any version of Beetl core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.15.13.RELEASE), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.ibeetl 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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Beetl core, 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

Before Beetl v3.15.13.RELEASE, the rendering template has a server-side template injection (SSTI) vulnerability. When the incoming template is controllable, it will be filtered by the DefaultNativeSecurityManager blacklist. Because blacklist filtering is not strict, the blacklist can be bypassed, leading to arbitrary code execution.
