Executive Summary

JeecgBoot through version 3.9.5 has a missing authorization vulnerability in the OssFileController queryById handler. This allows low-privileged authenticated users to read object storage file records by requesting GET /sys/oss/file/queryById with a known record ID. Attackers can then obtain original file names and direct storage URLs of files uploaded by other users.

Detection Guidance

Check for unauthorized access attempts to GET /sys/oss/file/queryById endpoints. Monitor logs for requests with record IDs that return file metadata or URLs. Verify if low-privileged users can retrieve file records they shouldn't access.

Impact Analysis

This vulnerability allows unauthorized users to access sensitive file information, including original file names and storage URLs. This could lead to data leaks, unauthorized access to confidential files, or potential further exploitation if the files contain sensitive or proprietary data.

Compliance Impact

This vulnerability could violate compliance requirements such as GDPR (data protection) or HIPAA (health information privacy) by enabling unauthorized access to sensitive data. Organizations may face legal penalties, reputational damage, and loss of trust due to non-compliance with data protection regulations.

Mitigation Strategies

Upgrade JeecgBoot to version 3.9.6 or later. Implement strict access controls to restrict GET /sys/oss/file/queryById to authorized users only. Review and remove unnecessary permissions for low-privileged accounts.
