| Title | PHPGurukul PHPGurukul Small Customer Relationship Management v4.0 Missing Authorization |
|---|
| Description | A critical vulnerability has been found in PHPGurukul Small CRM 4.0 application where the authorization mechanism fails to verify user roles before serving administrative content. The application only checks if a user is authenticated but does not verify their authorization level.
Any authenticated user can access administrative functions by directly navigating to admin URLs (e.g., /crm/admin/home.php, /crm/admin/edit-user.php) without any role verification. This allows complete privilege escalation from regular user to administrator, enabling unauthorized access to sensitive data, user modification, and system compromise.
An authenticated attacker with low-level user privileges can gain complete administrative access to the application, view and modify all user data, escalate privileges, and compromise the entire system. |
