Executive Summary

TIM Flow before version 26.0.6 has an improper authorization flaw in its dashboard Excel export endpoint. Any authenticated user can submit arbitrary SQL queries to this endpoint, which is meant only for administrators. This allows bypassing role-based access controls to retrieve sensitive database information as a downloadable spreadsheet.

Detection Guidance

Check TIM Flow version with command: tim-flow --version. If version is below 26.0.6, the system is vulnerable. Monitor network traffic for unauthorized Excel export requests to administrative endpoints.

Impact Analysis

An attacker with valid login credentials could exploit this to access confidential data stored in the database. This includes sensitive information that could be used for further attacks or data theft. The impact depends on the data stored but could be severe if the database contains personal or proprietary information.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations may face compliance violations, legal penalties, and reputational damage if sensitive data is exposed through this flaw.

Mitigation Strategies

Upgrade TIM Flow to version 26.0.6 or later immediately. Review and restrict access to dashboard export endpoints. Implement strict role-based access controls to prevent unauthorized SQL query submissions.
