Description

Snipe-IT is an IT asset/license management system. Prior to 8.6.3, any activated account can request /maintenances/{id} and read maintenance records for assets in the same company without asset or maintenance permission. app/Http/Controllers/MaintenancesController.php show() renders the record without authorize(), while company-scoped route-model binding only prevents access to other companies. Disclosed fields include asset tags, suppliers, purchase costs, notes, and dates. This issue is fixed in version 8.6.3.

Executive Summary

This vulnerability in Snipe-IT (versions prior to 8.6.3) allows any activated user within a company to access maintenance records for all assets in that company without proper permissions. The issue occurs because the show() method in MaintenancesController.php lacks authorization checks, exposing sensitive details like asset tags, suppliers, purchase costs, notes, and dates.

Detection Guidance

Check Snipe-IT version with: grep '"version"' /path/to/snipe-it/composer.json. If version is below 8.6.3, the system is vulnerable. Test access by attempting to view maintenance records via /maintenances/{id} with a low-privilege user account.

Impact Analysis

An attacker with activated access could view confidential maintenance records, including financial data (purchase costs), supplier information, and internal notes. This could lead to data leaks, competitive disadvantages, or misuse of asset management data within the organization.

Compliance Impact

This vulnerability may violate compliance requirements by exposing sensitive data without proper access controls. GDPR could be impacted if personal or financial data is leaked, while HIPAA may be at risk if maintenance records contain protected health information. Organizations must ensure proper authorization to meet regulatory standards.

Mitigation Strategies

Upgrade Snipe-IT to version 8.6.3 or later immediately. Verify the fix by checking that the MaintenancesController.php show() method includes $this->authorize('view', $maintenance->asset). Restrict user permissions to least privilege.
