# Positron Broadcast Signal Processor TRA7005 v1.20 _Passwd Exploit
#
#
# Vendor: Positron srl
# Product web page: https://www.positron.it
# https://www.positron.it/prodotti/apparati-broadcast/stereo-multicoder/tra-7005/
# Affected version: 1.20
# TRA7K5_REV107
# TRA7K5_REV106
# TRA7K5_REV104
# TRA7K5_REV102
#
# Summary: The TRA7000 series is a set of products dedicated to broadcast, designed to
# guarantee an excellent quality-price ratio in compliance with current regulations and
# intended for individual broadcasters or radio networks. All models in the TRA7000 series
# are fully digital, using only high-quality components such as 24-bit A/D and D/A converters
# and 32-bit DSP. The TRA7005 performs the functions of Stereo Coder, RDS Coder, 5-output
# MPX Distributor, AGC (adjustable) for both analogue and digital audio inputs, Clipper
# for both analogue and digital audio inputs, change-over emergency switching between any
# input with adjustable thresholds and intervention times, both in the switching phase on
# the secondary source and in the return phase to the primary source. Ethernet connection
# with Web-Server (optional) for total control and management of the device. Advanced BYPASS
# system between MPX input and outputs, active on operating and power supply anomalies and
# can also be activated remotely.
#
# Desc: The Positron Broadcast Digital Signal Processor TRA7005 suffers from an authentication
# bypass through a direct and unauthorized access to the password management functionality.
# The vulnerability allows attackers to bypass Digest authentication by manipulating the
# password endpoint _Passwd.html and its payload data to set a user's password to arbitrary
# value or remove it entirely. This grants unauthorized access to protected areas (/user,
# /operator, /admin) of the application without requiring valid credentials, compromising
# the device's system security.
#
# Tested on: Positron Web Server
#
#
# Vulnerability discovered by Gjoko 'LiquidWorm' Krstic
