How to Fix CVE-2020-17532

To remediate this vulnerability, upgrade all affected Java chassis 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.apache.servicecomb:java-chassis fixed: 1.3.2 
<dependency>
    <groupId>org.apache.servicecomb</groupId>
    <artifactId>java-chassis</artifactId>
    <version>1.3.2</version>
</dependency>
org.apache.servicecomb:java-chassis fixed: 2.1.5 
<dependency>
    <groupId>org.apache.servicecomb</groupId>
    <artifactId>java-chassis</artifactId>
    <version>2.1.5</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.apache.servicecomb

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-17532, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.servicecomb

Analyze the terminal output to locate any version of Java chassis in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.servicecomb 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Java chassis, 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

When handler-router component is enabled in servicecomb-java-chassis, authenticated user may inject some data and cause arbitrary code execution. The problem happens in versions between 2.0.0 ~ 2.1.3 and fixed in Apache ServiceComb-Java-Chassis 2.1.5
