1. EXECUTIVE SUMMARY
o CVSS v3 9.8
o ATTENTION: Exploitable remotely/low attack complexity
o Vendor: MiCODUS
o Equipment: MV720 GPS tracker
o Vulnerabilities: Use of Hard-coded Credentials, Improper Authentication,
Cross-site Scripting, Authorization Bypass Through User-controlled Key
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could allow an attacker
control over any MV720 GPS tracker, granting access to location, routes, fuel
cutoff commands, and the disarming of various features (e.g., alarms).
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of MV720 GPS tracker are affected:
o MV720 model
3.2 VULNERABILITY OVERVIEW
3.2.1 USE OF HARD-CODED CREDENTIALS CWE-798
The API server has an authentication mechanism that allows devices to use a
hard-coded master password. This may allow an attacker to send SMS commands
directly to the GPS tracker as if they were coming from the GPS owner's mobile
number.
CVE-2022-2107 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.2 IMPROPER AUTHENTICATION CWE-287
SMS-based GPS commands can be executed without authentication.
CVE-2022-2141 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.3 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE
SCRIPTING') CWE-79
The main web server has a reflected cross-site scripting vulnerability that
could allow an attacker to gain control by tricking a user into making a
request.
CVE-2022-2199 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:H/PR:N/UI:R/S:U/
C:H/I:H/A:H ).
3.2.4 AUTHORIZATION BYPASS THROUGH USER-CONTROLLED KEY CWE-639
The main web server has an authenticated insecure direct object reference
vulnerability on endpoint and parameter device IDs, which accept arbitrary
device IDs without further verification.
CVE-2022-34150 has been assigned to this vulnerability. A CVSS v3 base score of
7.1 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:L/UI:N/S:U/
C:H/I:L/A:N ).
3.2.5 AUTHORIZATION BYPASS THROUGH USER-CONTROLLED KEY CWE-639
The main web server has an authenticated insecure direct object references
vulnerability on endpoint and POST parameter "Device ID," which accepts
arbitrary device IDs.
CVE-2022-33944 has been assigned to this vulnerability. A CVSS v3 base score of
6.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:L/UI:N/S:U/
C:H/I:N/A:N ).
3.3 BACKGROUND
o CRITICAL INFRASTRUCTURE SECTORS: Transportation Systems, Government
Facilities, Financial Services, Critical Manufacturing
o COUNTRIES/AREAS DEPLOYED: Worldwide
o COMPANY HEADQUARTERS LOCATION: China
3.4 RESEARCHER
Pedro Umbelino, Dan Dahlberg, and Jacob Olcott of BitSight reported these
vulnerabilities to CISA.
4. MITIGATIONS
As of July 18th, 2022, MiCODUS has not provided updates or patches to mitigate
these vulnerabilities. CISA will update the corresponding ICSA to reflect any
patches, updates, or mitigation information provided by MiCODUS in the future.
CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability these vulnerabilities. Specifically, users
should:
o Minimize network exposure for all control system devices and/or systems,
and ensure they are not accessible from the Internet .
o Locate control system networks and remote devices behind firewalls and
isolate them from business networks.
o When remote access is required, use secure methods, such as Virtual Private
Networks (VPNs), recognizing VPNs may have vulnerabilities and should be
updated to the most current version available. Also recognize VPN is only
as secure as its connected devices.
CISA also recommends users take the following measures to protect themselves
from social engineering attacks:
o Do not click web links or open unsolicited attachments in email messages.
o Refer to Recognizing and Avoiding Email Scams for more information on
avoiding email scams.
o Refer to Avoiding Social Engineering and Phishing Attacks for more
information on social engineering attacks.
CISA reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices
on the ICS webpage at cisa.gov/ics . Several CISA products detailing cyber
defense best practices are available for reading and download, including
Improving Industrial Control Systems Cybersecurity with Defense-in-Depth
Strategies .
Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage at cisa.gov/ics in the technical information paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies .
Organizations observing suspected malicious activity should follow established
internal procedures and report findings to CISA for tracking and correlation
against other incidents.
No known public exploits specifically target these vulnerabilities.
