How to Fix CVE-2018-20595

To remediate this vulnerability, upgrade all affected Hsweb commons 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.hswebframework.web:hsweb-commons fixed: Latest secure release

<dependency>
    <groupId>org.hswebframework.web</groupId>
    <artifactId>hsweb-commons</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.hswebframework.web

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-20595, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.hswebframework.web

Analyze the terminal output to locate any version of Hsweb commons 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.hswebframework.web 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Hsweb commons, 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

A CSRF issue was discovered in web/authorization/oauth2/controller/OAuth2ClientController.java in hsweb 3.0.4 because the state parameter in the request is not compared with the state parameter in the session after user authentication is successful.
