Cisco ONS multiple devices could allow file upload and retrieval

cisco-ons-file-upload (15264) The risk level is classified as MediumMedium Risk


Multiple Cisco ONS devices could allow a remote attacker to upload and retrieve the ONS system files. A remote unauthenticated attacker could establish a connection to the Trivial File Transfer Protocol (TFTP) service listening on UDP port 69 and issue GET and PUT commands to retrieve or upload ONS system files to the current archive in the /flash0 or /flash1 directories. An attacker could use this vulnerability to upload malicious ONS files and launch a denial of service attack against the affected device.
