How to Fix CVE-2017-1000217

To remediate this vulnerability, upgrade all affected Base 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.opencastproject:base fixed: 2.3.3 
<dependency>
    <groupId>org.opencastproject</groupId>
    <artifactId>base</artifactId>
    <version>2.3.3</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=org.opencastproject

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-1000217, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.opencastproject

Analyze the terminal output to locate any version of Base in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.opencastproject 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Base, 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

Opencast 2.3.2 and older versions are vulnerable to script injections through media and metadata in the player and media module resulting in arbitrary code execution, fixed in 2.3.3 and 3.0.
