CVE-2024-27348: 
Java vulnerability analysis and mitigation

CVE-2024-27348 is a critical Remote Command Execution (RCE) vulnerability affecting Apache HugeGraph-Server versions from 1.0.0 before 1.3.0 in both Java8 and Java11 environments. The vulnerability was disclosed in late April 2024 and has been assigned a CVSS v3.1 score of 9.8 (Critical) (NVD). The flaw specifically exists in the Gremlin graph traversal language API of HugeGraph-Server (Apache Advisory).

The vulnerability has been classified as a Remote Command Execution (RCE) flaw that enables attackers to bypass sandbox restrictions and achieve code execution, providing complete control over vulnerable servers (Hacker News). The vulnerability received a critical CVSS v3.1 base score of 9.8 with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and no required privileges or user interaction (NVD).

The vulnerability allows attackers to execute arbitrary commands remotely on affected servers, potentially leading to complete system compromise. The critical severity rating and inclusion in CISA's Known Exploited Vulnerabilities Catalog underscores its significant security impact (CISA Alert).

Users are strongly recommended to upgrade to version 1.3.0 with Java11 and enable the Auth system to remediate this vulnerability. Additionally, users can enable the 'Whitelist-IP/port' function to improve the security of RESTful-API execution (Apache Advisory). For versions prior to 1.5.0, users should also manually set the JWT token's secretKey in the rest-server.properties file to address related security concerns (HugeGraph Docs).

The vulnerability has garnered significant attention from the security community, leading to its inclusion in CISA's Known Exploited Vulnerabilities Catalog on September 18, 2024, with a remediation due date of October 9, 2024 (CISA Alert).
