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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.89%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
