Technical details
A broken access control vulnerability exists in CtrlPanel versions 1.1.1 and prior due to missing authorization checks in several administrative controllers. While the application correctly verifies permissions when displaying web forms (GET requests), it fails to perform equivalent checks on the corresponding 'store' and 'update' methods (POST/PATCH requests). An authenticated attacker can bypass Role-Based Access Control (RBAC) by sending direct HTTP requests to these endpoints. Affected components include controllers for coupons, vouchers, user accounts, and server management. Exploitation allows for privilege escalation, unauthorized modification of financial records, and manipulation of server ownership. The issue is resolved in version 1.2.0.
