Advisory Summary

CVE-2023-6307 is a MODERATE (CVSS 6.3) security vulnerability vulnerability (CWE-23: Relative Path Traversal) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2023-6307

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-2023-6307, 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-23: Relative Path Traversal, where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. 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

A vulnerability classified as critical was found in jeecgboot JimuReport up to 1.6.1. Affected by this vulnerability is an unknown functionality of the file /download/image. The manipulation of the argument imageUrl leads to relative path traversal. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-246133 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
