Successful exploitation of these vulnerabilities could allow an attacker to gain control of the device, escalate privileges, or execute arbitrary code.
Swisslog Healthcare reports the vulnerabilities affect the following Translogic Pneumatic Tube Systems:
User and root accounts have hardcoded passwords that can be accessed remotely on the Nexus Control Panel. These accounts are enabled by default and cannot be turned off by native configuration of the system.
CVE-2021-37163 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).
A user logged in using the default credentials can gain root access to the device, which allows permissions for all the functionalities of the device.
CVE-2021-37167 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
A buffer overflow allows an attacker to overwrite an internal queue data structure, which could allow remote code execution.
CVE-2021-37161 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).
A buffer overflow allows an attacker to overwrite an internal queue data structure, which could allow remote code execution.
CVE-2021-37162 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).
A specially crafted message to the HMI may cause an overflow, which could allow remote code execution.
CVE-2021-37165 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).
Received data can be copied to a stack buffer, resulting in an overflow.
CVE-2021-37164 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 method used to bind a local service to ports on device interfaces may allow the connection to be hijacked by an external attacker.
CVE-2021-37166 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).
There is no file validation during an upload for an update.
CVE-2021-37160 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:H/A:N).
Barak Hadad and Ben Seri from Armis reported these vulnerabilities to Swisslog.
Swisslog Healthcare recommends upgrading to the latest software version as soon as it becomes available. Version 7.2.5.7 is reported to fix all vulnerabilities above except CVE-2021-37160. Use the latest version together with mitigation methods below to protect against exploitation of all the listed vulnerabilities.
Swisslog also recommends the following mitigation methods until updated software is deployed:
Armis recommends the following practices to identify and block attempts to exploit these issues.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
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 on us-cert.cisa.gov. Several recommended 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 on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01BβTargeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
No known public exploits specifically target these vulnerabilities.
