-----BEGIN PGP SIGNED MESSAGE-----  
Hash: SHA512  
  
Advisory ID: SYSS-2024-042  
Product: DiCal-RED  
Manufacturer: Swissphone Wireless AG  
Affected Version(s): Unknown  
Tested Version(s): 4009  
Vulnerability Type: Exposure of Sensitive Information to an Unauthorized Actor (CWE-200)  
Risk Level: Medium  
Solution Status: Open  
Manufacturer Notification: 2024-04-16  
Solution Date: None  
Public Disclosure: 2024-08-20  
CVE Reference: CVE-2024-36441  
Author of Advisory: Sebastian Hamann, SySS GmbH  
  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Overview:  
  
DiCal-RED is a radio module for communication between emergency vehicles and  
control rooms. It provides Ethernet, Wi-Fi and cellular network connectivity  
and runs a Linux- and BusyBox-based operating system.  
  
The manufacturer describes the product as follows (see [1]):  
  
"The DiCal-Red radio data module reliably guides you to your destination. This  
is ensured by the linking of navigation (also for the transmission of position  
data) and various radio modules."  
  
Due to missing authentication checks, the device is vulnerable to the  
disclosure of sensitive information.  
  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Vulnerability Details:  
  
The device provides a network server on TCP port 2101. This service does not  
seem to process any input, but it regularly sends data to connected clients.  
This includes operation messages when they are processed by the device.  
An unauthenticated attacker can therefore gain information about current  
emergency situations and possibly also emergency vehicle positions or routes.  
  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Proof of Concept (PoC):  
  
$ telnet <IP or hostname> 2101  
[Wait ...]  
  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Solution:  
  
The manufacturer recommends not running the device in an untrusted network.
