Description
Authorization Bypass Through User-Controlled Key in the ticket management component in Roskus Prospero Flow CRM before 5.4.9 allows authenticated users of any company to read the full content (title, description, and attachments) of tickets belonging to another company, to hijack another company's tickets by reassigning their company_id, and to delete another company's tickets without any authorization check, via the ticket's numeric identifier, because the read and save operations retrieve the record without constraining the query to the authenticated user's company, and the delete controller type-hints a generic Illuminate\Http\Request instead of the TicketDeleteRequest that would enforce the required permission.

Executive Summary

This is an Authorization Bypass Through User-Controlled Key vulnerability in Roskus Prospero Flow CRM before version 5.4.9. It allows authenticated users from any company to read, hijack, or delete tickets belonging to other companies by manipulating the ticket's numeric identifier. The flaw exists because the system fails to enforce company-specific access controls during read, update, and delete operations.

Detection Guidance

To detect this vulnerability, check if your Prospero Flow CRM version is 5.4.8 or earlier. Verify if unauthenticated users can access or modify tickets across different companies by testing endpoints like GET /ticket/update/{id}, POST /ticket/save, and GET /ticket/delete/{id} with varying company_id values.

Impact Analysis

An attacker could access sensitive ticket information including titles, descriptions, and attachments from other companies. They could reassign tickets to their own company, effectively hijacking them, or delete tickets entirely without authorization. This could lead to data breaches, loss of critical business information, and disruption of operations for affected companies.

Compliance Impact

This vulnerability could violate GDPR by enabling unauthorized access to personal data in tickets, potentially leading to data breaches. For HIPAA, if tickets contain protected health information, unauthorized access or deletion could result in compliance violations. Organizations using affected versions may face regulatory penalties and reputational damage.

Mitigation Strategies

Immediately upgrade Prospero Flow CRM to version 5.4.9 or higher. Ensure the latest security patches are applied to enforce company_id filtering in ticket operations and verify proper authorization checks in TicketUpdateController, TicketRepository, and TicketDeleteController.
