Advisory Summary

CVE-2016-20095 is a HIGH (CVSS 7.8) security vulnerability vulnerability (CWE-428: Unquoted Search Path or Element) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. this can cause the product to access resources in a parent path.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2016-20095

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-2016-20095, 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-428: Unquoted Search Path or Element, where the product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. this can cause the product to access resources in a parent path. 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

Matrix42 Remote Control Host 3.20.0031 contains an unquoted service path vulnerability in the FastViewerRemoteService and FastViewerRemoteProxy services that allows local users to execute arbitrary code with SYSTEM privileges. Attackers can place a malicious executable in the Program Files directory with a crafted name to be executed by the service during startup, gaining elevated privileges.
