Attack-Flow Graph

Executive Summary

JeecgBoot through version 3.9.5 has a missing authorization vulnerability in the SysDepartController appImportExcel handler. This allows any authenticated user, even with low privileges, to import departments by uploading a crafted Excel file to the POST /sys/sysDepart/appImportExcel endpoint. This can create arbitrary sys_depart records in the administrator-maintained department tree.

Detection Guidance

Check for unauthorized POST requests to /sys/sysDepart/appImportExcel with Excel file uploads. Monitor logs for suspicious activity from low-privileged users creating or modifying department records.

Impact Analysis

Low-privileged attackers could exploit this to add unauthorized departments to the system, potentially disrupting organizational structure or enabling further attacks by manipulating the department hierarchy.

Compliance Impact

This vulnerability allows low-privileged attackers to create arbitrary department records, which could enable unauthorized data access or manipulation. For GDPR, this may violate principles of data integrity and access control. For HIPAA, it could compromise protected health information integrity if department structures relate to PHI access permissions.

Mitigation Strategies

Immediately restrict access to /sys/sysDepart/appImportExcel endpoint. Update JeecgBoot to version 3.9.5 or later. Implement strict input validation for Excel uploads and enforce role-based access controls.
