How to Fix CVE-2017-15683

To remediate this vulnerability, upgrade all affected Crafter core 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.craftercms:crafter-core fixed: 3.0.1 
<dependency>
    <groupId>org.craftercms</groupId>
    <artifactId>crafter-core</artifactId>
    <version>3.0.1</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.craftercms

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-15683, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.craftercms

Analyze the terminal output to locate any version of Crafter core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.craftercms 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-91: XML Injection (aka Blind XPath Injection), where the product does not properly neutralize special elements that are used in xml, allowing attackers to modify the syntax, content, or commands of the xml before it is processed by an end system. In Crafter core, 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 Crafter CMS Crafter Studio 3.0 prior to 3.0.1 an unauthenticated attacker is able to create a site with specially crafted XML that allows the retrieval of OS files out-of-band.
