How to Fix CVE-2019-10249

To remediate this vulnerability, upgrade all affected Org.eclipse.xtext 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.eclipse.xtext:org.eclipse.xtext fixed: 2.18.0 
<dependency>
    <groupId>org.eclipse.xtext</groupId>
    <artifactId>org.eclipse.xtext</artifactId>
    <version>2.18.0</version>
</dependency>
org.eclipse.xtend:org.eclipse.xtend.core fixed: 2.18.0 
<dependency>
    <groupId>org.eclipse.xtend</groupId>
    <artifactId>org.eclipse.xtend.core</artifactId>
    <version>2.18.0</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.eclipse.xtext

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-10249, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.eclipse.xtext

Analyze the terminal output to locate any version of Org.eclipse.xtext in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.18.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.eclipse.xtext 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-319: Cleartext Transmission of Sensitive Information, where the product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors. In Org.eclipse.xtext, 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

All Xtext & Xtend versions prior to 2.18.0 were built using HTTP instead of HTTPS file transfer and thus the built artifacts may have been compromised.
