Description Preview
A Cross-site Scripting (XSS) vulnerability has been identified in all versions of com.xuxueli:xxl-job. The vulnerability exists in the user management functionality of the XXL-JOB admin interface. Attackers can inject and execute malicious HTML and JavaScript code through the /xxl-job-admin/user/add and /xxl-job-admin/user/update endpoints. This vulnerability could allow attackers to steal sensitive information, hijack user sessions, or perform actions on behalf of legitimate users.
Overview
XXL-JOB is a distributed task scheduling framework. The vulnerability (CWE-79) exists because the application does not properly sanitize or validate user input in the user management functionality. When adding or updating user information through the admin interface, an attacker can inject malicious HTML or JavaScript code that will be stored in the application and executed when viewed by other users, particularly administrators. This stored XSS vulnerability could lead to unauthorized access, data theft, or complete compromise of the XXL-JOB admin interface.
Remediation
As no patch is currently available for this vulnerability, administrators should implement the following mitigations:
- Restrict access to the XXL-JOB admin interface, particularly the user management functionality, to trusted networks and users only.
- Implement additional security controls such as a Web Application Firewall (WAF) configured to detect and block XSS attacks.
- Consider implementing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts.
- Regularly monitor logs for suspicious activities related to the user management endpoints.
- Keep monitoring for updates from the XXL-JOB developers for an official patch.
- If possible, consider implementing your own input validation and output encoding for the vulnerable endpoints.
