In versions 4.3.2-R4 and prior of Cambium Networks cnPilot firmware, although the option to access the configuration file is not available in the normal web administrative console for the 'user' account, the configuration file is accessible via direct object reference (DRO) at http://<device-ip-or-hostname>/goform/down_cfg_file by this otherwise low privilege 'user' account.
The web application does not sufficiently verify inputs that are assumed to be immutable but are actually externally controllable, such as hidden form fields.
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
