Technical details
The vulnerability stems from missing per-instruction authorization checks within the router's firmware. Specifically, the system fails to evaluate permissions for multiple internal operation codes (opcodes). An attacker with network access and low-level privileges can exploit this lack of Role-Based or Attribute-Based Access Control (RBAC/ABAC) to execute sensitive operations, install unauthorized software, or run arbitrary commands. Acer has indicated that a resolution involves introducing RBAC/ABAC at every opcode layer and implementing audit logging for sensitive operations.
