Apache HugeGraph Gremlin Remote Code Execution (CVE-2024-27348)
Overview
Apache HugeGraph Gremlin Remote Code Execution, tracked as CVE-2024-27348, affects Apache HugeGraph-Server deployments where command execution is possible through Gremlin-related server behavior. HugeGraph is a graph database platform, so compromise of the server can expose graph data, application integrations, and backend infrastructure.
Vulnerability Overview
CVE-2024-27348 is described by Apache as a remote command execution vulnerability in Apache HugeGraph-Server. The issue affects HugeGraph-Server from 1.0.0 before 1.3.0 when running with Java 8 or Java 11.
The vulnerability is associated with command execution in Gremlin server functionality and insufficient access control around the affected behavior. Apache recommends upgrading to HugeGraph-Server 1.3.0 with Java 11 and enabling the authentication system.
Impact
The vulnerability is rated Critical with a CVSS 3.1 score of 9.8. Successful exploitation can allow unauthenticated remote code execution with high confidentiality, integrity, and availability impact.
CVE-2024-27348 is listed in the CISA Known Exploited Vulnerabilities catalog, so exposed vulnerable HugeGraph-Server deployments should be prioritized for remediation.
Vulnerability Scope
The affected range is Apache HugeGraph-Server 1.0.0 through before 1.3.0 on Java 8 and Java 11. Fixed deployments should upgrade to HugeGraph-Server 1.3.0, use Java 11, and enable authentication according to Apache guidance.
The highest-risk systems are HugeGraph-Server instances reachable by untrusted users with Gremlin-related functionality exposed and authentication not properly enforced.
Lab Focus
This Hackviser lab focuses on understanding how graph query execution features can become a remote code execution path when authorization boundaries are weak. You will practice identifying affected HugeGraph versions, recognizing the Gremlin execution surface, and mapping the CVE details to secure database service deployment.
