Executive Summary

This is a Cross-Site Scripting (XSS) vulnerability in XXL-JOB versions up to 3.4.2/3.5.0. It allows normal users to inject malicious JavaScript code into the name and author parameters of the '/jobinfo/insert' interface. When an administrator views the task management interface, the injected code executes, potentially stealing sensitive information like cookies.

Detection Guidance

To detect this XSS vulnerability in XXL-JOB, monitor HTTP requests to the '/jobinfo/insert' endpoint for suspicious payloads in the 'name' or 'author' parameters. Check if the XssUtil filter fails to block event handlers like 'oncopy' or 'onmousemove'. Review task management interfaces for unexpected JavaScript execution.

Impact Analysis

An attacker can create a regular user account, add a task with malicious payloads, and trigger the vulnerability when the admin accesses the interface. This could lead to theft of sensitive data such as session cookies, unauthorized actions on behalf of the admin, or further compromise of the system.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR's data protection principles and HIPAA's security requirements. Organizations may face compliance breaches, legal penalties, and reputational damage if sensitive data is exposed due to this XSS flaw.

Mitigation Strategies

Upgrade XXL-JOB to a version beyond 3.5.0 where the XSS vulnerability is patched. Implement stricter input validation for the 'name' and 'author' parameters. Enhance the XssUtil filter to block all event handlers and JavaScript-related payloads. Restrict regular user permissions to prevent task creation with malicious inputs.
