Contec Health CMS8000
A threat actor with momentary access to the device can plug in a USB drive and perform a malicious firmware update, resulting in permanent changes to device functionality. No authentication or controls are in place to prevent a threat actor from maliciously modifying firmware and performing a drive-by attack to load the firmware on any CMS8000 device.CVE-2022-36385 has been assigned to this vulnerability. A CVSS v3 base score of 6.8 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The CMS800 device fails while attempting to parse malformed network data sent by a threat actor. A threat actor with network access can remotely issue a specially formatted UDP request that will cause the entire device to crash and require a physical reboot. A UDP broadcast request could be sent that causes a mass denial-of-service attack on all CME8000 devices connected to the same network.CVE-2022-38100 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:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Multiple globally default credentials exist across all CMS8000 devices, that once exposed, allow a threat actor with momentary physical access to gain privileged access to any device. Privileged credential access enables the extraction of sensitive patient information or modification of device parameters.CVE-2022-38069 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Multiple binary application files on the CMS8000 device are compiled with 'not stripped' and 'debug_info' compilation settings. These compiler settings greatly decrease the level of effort for a threat actor to reverse engineer sensitive code and identify additional vulnerabilities.CVE-2022-38453 has been assigned to this vulnerability. A CVSS v3 base score of 3.0 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N). The CMS8000 device does not properly control or sanitize the SSID name of a new Wi-Fi access point. A threat actor could create an SSID with a malicious name, including non-standard characters that, when the device attempts connecting to the malicious SSID, the device can be exploited to write arbitrary files or display incorrect information.CVE-2022-3027 has been assigned to this vulnerability. A CVSS v3 base score of 5.7 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).
