Attack-Flow Graph

Executive Summary

JeecgBoot through version 3.9.5 has a missing authorization vulnerability in the QuartzJobController queryById handler. This flaw allows low-privileged authenticated users to read scheduled job records by sending a GET request to /sys/quartzJob/queryById with a job ID. Attackers can retrieve sensitive job details such as class names, cron expressions, parameters, and status that are meant for administrators only.

Detection Guidance

Check for unauthorized access to the QuartzJobController endpoint by monitoring GET requests to /sys/quartzJob/queryById. Look for low-privileged users retrieving job details like class names, cron expressions, or parameters.

Impact Analysis

This vulnerability can allow unauthorized users to view sensitive job configurations and schedules. Attackers may gain insights into system operations, potentially leading to further exploitation or data breaches. The impact is limited to information disclosure and does not directly allow code execution or data modification.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR or HIPAA by exposing sensitive job data that may include personal or health information. Unauthorized access to such data violates confidentiality requirements and could result in regulatory penalties or legal consequences.

Mitigation Strategies

Upgrade JeecgBoot to a version beyond 3.9.5 to patch the missing authorization flaw. Restrict access to the /sys/quartzJob/queryById endpoint to admin-only users. Review logs for suspicious queries to this endpoint.
