Successful exploitation of these vulnerabilities could cause a denial-of-service condition, allow full control of robot functions, or expose sensitive information.
Aethon reports these vulnerabilities affect the following versions of TUG Home Base Server, a server used to control and communicate with autonomous mobile robots in hospitals:
An unauthenticated attacker can arbitrarily add new users with administrative privileges and delete or modify existing users.
CVE-2022-1066 has been assigned to this vulnerability. A CVSS v3 base score of 8.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N).
An unauthenticated attacker can freely access hashed user credentials.
CVE-2022-26423 has been assigned to this vulnerability. A CVSS v3 base score of 8.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N).
An unauthenticated attacker can connect to the TUG Home Base Server websocket to take control of TUG robots.
CVE-2022-1070 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 “Reports” tab of the Fleet Management Console is vulnerable to stored cross-site scripting attacks when new reports are created or edited.
CVE-2022-27494 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:L).
The “Load” tab of the Fleet Management Console is vulnerable to reflected cross-site scripting attacks.
CVE-2022-1059 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:L).
Asher Brass and Daniel Brodie of Cynerio reported these vulnerabilities to CISA.
Aethon has implemented a mitigation plan to address these vulnerabilities. Aethon has checked all locations where this product is in use to ensure firewalls are active and to update systems to the newest software (Version 24).
