# Vendor: DB Elettronica Telecomunicazioni SpA
# Product web page: https://www.screen.it | https://www.dbbroadcast.com
# https://www.dbbroadcast.com/products/radio/sft-dab-series-compact-air/
# Affected version: Firmware: 1.9.3
# Bios firmware: 7.1 (Apr 19 2021)
# Gui: 2.46
# FPGA: 169.55
# uc: 6.15
#
# Summary: Screen's new radio DAB Transmitter is reaching the highest
# technology level in both Digital Signal Processing and RF domain.
# SFT DAB Series - Compact Radio DAB Transmitter - Air. Thanks to the
# digital adaptive precorrection and configuatio flexibility, the Hot
# Swap System technology, the compactness and the smart system design,
# the SFT DAB are advanced transmitters. They support standards DAB,
# DAB+ and T-DMB and are compatible with major headend brands.
#
# Desc: The application suffers from a weak session management that can
# allow an attacker on the same network to bypass these controls by reusing
# the same IP address assigned to the victim user (NAT) and exploit crucial
# operations on the device itself. By abusing the IP address property that
# is binded to the Session ID, one needs to await for such an established
# session and issue unauthorized requests to the vulnerable API to manage
# and/or manipulate the affected transmitter.
#
# Tested on: Keil-EWEB/2.1
# MontaVistaยฎ Linuxยฎ Carrier Grade eXpress (CGX)
