Hash: SHA512<\/p>\n
Advisory ID: SYSS-2024-040
Product: DiCal-RED
Manufacturer: Swissphone Wireless AG
Affected Version(s): Unknown
Tested Version(s): 4009
Vulnerability Type: Improper Authentication (CWE-287)
Risk Level: High
Solution Status: Open
Manufacturer Notification: 2024-04-16
Solution Date: None
Public Disclosure: 2024-08-20
CVE Reference: CVE-2024-36444
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 improper authentication checks, the device is vulnerable to
unauthorized access to logs and other files on the device’s file system.<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Vulnerability Details:<\/p>\n
The device allows viewing log files via the administrative web interface.
This function does not require an authenticated session.<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Proof of Concept (PoC):<\/p>\n
As other parts of the administrative web interface do require authentication,
a simple proof of concept is to log in to the web interface and navigate to
the function to view log files.
Log file contents are returned by a URL similar to
http:\/192.0.2.1\/cgi-bin\/fdmcgiwebv2.cgi?action=displayfilel&data={%22FilePath%22:%22%22,%22FileAlias%22:%22FdmDebugPath%22,%22LinesMax%22:0}<\/p>\n
Using a local proxy to remove the QSESSIONID cookie from this request shows
that the content is also returned when not sending any session information.<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Solution:<\/p>\n
The manufacturer recommends not running the device in an untrusted network.<\/p>\n
