url/goform/traceroute↗

→The file path traversal vulnerability is accessible to ALL authenticated users (not just admins) via the 'ping' and 'traceroute' functions of the web administrative console on Cambium cnPilot r200/r201 devices. ↗
→Monitor HTTP requests to Cambium cnPilot web admin console targeting traceroute/ping form endpoints with path traversal sequences (e.g., ../../) in parameters, which can be used to read arbitrary files from the filesystem. ↗

·The NVD advisory states affected versions as '4.3.2-R4 and prior', while the Metasploit module lists '4.3.3-R4 and prior'. Verify the exact boundary version against the vendor advisory before scoping detection. ↗
·Exploitation requires authentication; detection should focus on authenticated sessions making anomalous traversal requests, not unauthenticated probes. ↗
