How to Fix CVE-2018-12540

To remediate this vulnerability, upgrade all affected Vertx web dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.vertx:vertx-web fixed: 3.5.3
<dependency>
    <groupId>io.vertx</groupId>
    <artifactId>vertx-web</artifactId>
    <version>3.5.3</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=io.vertx

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-12540, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.vertx

Analyze the terminal output to locate any version of Vertx web in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.5.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.vertx 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 Vertx web, 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

In version from 3.0.0 to 3.5.2 of Eclipse Vert.x, the CSRFHandler do not assert that the XSRF Cookie matches the returned XSRF header/form parameter. This allows replay attacks with previously issued tokens which are not expired yet.
