How to Fix CVE-2019-17561

To remediate this vulnerability, upgrade all affected Netbeans 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.mevenide:netbeans fixed: Latest secure release 
<dependency>
    <groupId>org.codehaus.mevenide</groupId>
    <artifactId>netbeans</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.mevenide

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-17561, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Netbeans 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.mevenide 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Netbeans, 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

The "Apache NetBeans" autoupdate system does not fully validate code signatures. An attacker could modify the downloaded nbm and include additional code. "Apache NetBeans" versions up to and including 11.2 are affected by this vulnerability. NetBeans releases before the Apache transition started may also be affected.
