| Título | xuxueli XXL-JOB 3.4.2 Improper Control of Generation of Code |
|---|
| Descripción | A vulnerability was found in Xuxueli xxl-job version 3.4.2. It has been classified as critical. The affected component is the GlueFactory class in xxl-job-core/src/main/java/com/xxl/job/core/glue/GlueFactory.java. The function GroovyClassLoader.parseClass() compiles user-provided Groovy source code without any sandbox restrictions. No SecureASTCustomizer or CompilerConfiguration is applied, allowing arbitrary Java/Groovy code execution including Runtime.exec(). This vulnerability allows Remote Code Execution (RCE) via the web interface without requiring administrator access. A normal authenticated user with jobGroup permissions can create a GLUE_GROOVY type job containing arbitrary malicious code, which executes on the executor server with full system privileges. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. |
