How to Fix CVE-2023-33546

To remediate this vulnerability, upgrade all affected Janino parent 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.codehaus.janino:janino-parent fixed: Latest secure release 
<dependency>
    <groupId>org.codehaus.janino</groupId>
    <artifactId>janino-parent</artifactId>
    <version>Latest secure 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=org.codehaus.janino

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-33546, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.codehaus.janino

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

Note: The mvn dependency:tree -Dincludes=org.codehaus.janino 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-787: Out-of-bounds Write, where the product writes data past the end, or before the beginning, of the intended buffer. In Janino parent, 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

janino 3.1.9 and earlier is subject to denial of service (DOS) attacks when using the expression `evaluator.guess` parameter name method. If the parser runs on user-supplied input, an attacker could supply content that causes the parser to crash due to a stack overflow.
