CVE-2024-3366:
Java vulnerability analysis and mitigation
Overview
A vulnerability has been identified in Xuxueli xxl-job versions up to 2.4.1, affecting the deserialize function in the file com/xxl/job/core/util/JdkSerializeTool.java of the Template Handler component. The vulnerability was disclosed on April 6, 2024, and has been assigned identifier CVE-2024-3366 (NVD).
Technical details
The vulnerability is related to template injection in the FreeMarker template engine (version 2.3.32) used by xxl-job. The issue stems from the ability to exploit the core library utilities, particularly through the com/xxl/job/core/util/JdkSerializeTool.java component. The vulnerability has been assigned a CVSS v3.1 base score of 3.5 (LOW) with the vector string CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N (VulDB).
Impact
The vulnerability allows attackers to perform template injection attacks that could lead to code execution. Through exploitation of the core library utilities and FreeMarker template engine, attackers can potentially write malicious template files that, when rendered, could result in command execution (GitHub Issue).
Mitigation and workarounds
Users are advised to upgrade to a version newer than 2.4.1 when available and implement proper input filtering mechanisms. The vulnerability can be mitigated by carefully controlling access to template rendering functionality and implementing strict input validation (GitHub Issue).
