Arbitrary file write via path traversal
Published May 17, 2022 · Updated Apr 16, 2025
Path traversal in Cambium Networks cnMaestro On-Premises allows remote authenticated users to write arbitrary server files. A vulnerable route accepts ../ sequences in a supplied filename and passes the resulting unrestricted path to the server's file-save operation. Exploitation requires low-privileged access and user interaction, and permits attacker-chosen data to overwrite any server file.
