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

Public Disclosure: 2024-08-20
CVE Reference: CVE-2024-36441
Author of Advisory: Sebastian Hamann, SySS GmbH<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Overview:<\/p>\n
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.<\/p>\n
The manufacturer describes the product as follows (see [1]):<\/p>\n
“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.”<\/p>\n
Due to missing authentication checks, the device is vulnerable to the
disclosure of sensitive information.<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Vulnerability Details:<\/p>\n
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.<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Proof of Concept (PoC):<\/p>\n
$ telnet <IP or hostname> 2101
[Wait …]\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Solution:<\/p>\n
The manufacturer recommends not running the device in an untrusted network.<\/p>\n
