This updated advisory is a follow-up to the original advisory titled ICSA-22-200-01 MiCODUS MV720 GPS tracker that was published July 19, 2022, on the ICS webpage on cisa.gov/ICS
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).
The following versions of MV720 GPS tracker are affected:
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 ownerβs 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).
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).
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).
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).
The main web server has an authenticated insecure direct object references vulnerability on endpoint and POST parameter βDevice ID,β 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).
Pedro Umbelino, Dan Dahlberg, and Jacob Olcott of BitSight reported these vulnerabilities to CISA.
