In versions 4.3.2-R4 and prior of Cambium Networks cnPilot firmware, the 'ping' and 'traceroute' functions of the web administrative console expose a file path traversal vulnerability, accessible to all authenticated users.
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 uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
