How to Fix CVE-2019-9628

To remediate this vulnerability, upgrade all affected Xmltooling 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.opensaml:xmltooling fixed: 3.0.4 
<dependency>
    <groupId>org.opensaml</groupId>
    <artifactId>xmltooling</artifactId>
    <version>3.0.4</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.opensaml

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-9628, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.opensaml

Analyze the terminal output to locate any version of Xmltooling in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.opensaml 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-755: Improper Handling of Exceptional Conditions, where the product does not handle or incorrectly handles an exceptional condition. In Xmltooling, 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 XMLTooling library all versions prior to V3.0.4, provided with the OpenSAML and Shibboleth Service Provider software, contains an XML parsing class. Invalid data in the XML declaration causes an exception of a type that was not handled properly in the parser class and propagates an unexpected exception type.
