Advisory Summary

CVE-2019-20460 is a HIGH (CVSS 8.8) security vulnerability vulnerability (CWE-352: Cross-Site Request Forgery (CSRF)) affecting Software libraries in the Maven ecosystem. The weakness occurs when 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.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2019-20460

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

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

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-20460, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software 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 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 Software, 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

An issue was discovered on Epson Expression Home XP255 20.08.FM10I8 devices. POST requests don't require (anti-)CSRF tokens or other mechanisms for validating that the request is from a legitimate source. In addition, CSRF attacks can be used to send text directly to the RAW printer interface. For example, an attack could deliver a worrisome printout to an end user.
