Attack-Flow Graph

Executive Summary

JeecgBoot through version 3.9.5 has a missing authorization vulnerability in the SysTenantController listPackByTenantUserId handler. This flaw allows any authenticated user to query tenant product packs by supplying arbitrary tenantId and userId parameters. Attackers with low privileges can exploit this to enumerate any tenant's product pack configuration and identify which users are tenant administrators.

Detection Guidance

Check for unauthorized access to the SysTenantController listPackByTenantUserId endpoint by monitoring API logs for requests with arbitrary tenantId and userId parameters. Look for repeated queries that enumerate tenant configurations or user roles.

Impact Analysis

An attacker could exploit this to gather sensitive information about tenant configurations and user roles. This may lead to further attacks like privilege escalation or targeted phishing by knowing administrator identities. The impact is limited to information disclosure as no data modification or deletion is possible.

Compliance Impact

This vulnerability could lead to unauthorized access to tenant data, violating confidentiality requirements in GDPR and HIPAA. Organizations using JeecgBoot may face compliance violations due to insufficient access controls, potentially resulting in fines or legal consequences.

Mitigation Strategies

Update JeecgBoot to the latest version beyond 3.9.5 to patch the missing authorization flaw. Implement strict input validation for tenantId and userId parameters in API endpoints. Restrict access to sensitive endpoints to authorized users only.
