DHS Warns of Critical Flaws in Medtronic Medical Devices

[silversurfer]

Critical vulnerabilities impacting Medtronic Valleylab products could allow attackers to overwrite files and achieve remote code execution, the Department of Homeland Security (DHS) warns.
 
An advisory published by the DHS’s Cybersecurity & Infrastructure Security Agency (CISA) warns of three recently patched vulnerabilities in Medtronic Valleylab FT10 and FX8 devices that could allow attackers to install a non-root shell.
 
Although the network connections on these products should be disabled by default and the Ethernet port disabled upon reboot, network connectivity is often enabled, thus exposing them to attacks.
 
The impacted devices use multiple sets of hardcoded credentials that, if exposed, could allow attackers to read files, CISA’s advisory reads. Tracked as CVE-2019-13543, the first of these vulnerabilities has a base score of 5.8.
 
It was also discovered that the vulnerable products use the descrypt algorithm for OS password hashing. Although network-based logons are disabled, other vulnerabilities could be used to get local shell access and obtain these hashes. The issue is tracked as CVE-2019-13539 and has a CVSS score of 7.0.
 
Additionally, a vulnerable version of the rssh utility used in these products to facilitate file uploads could allow attackers to gain administrative access to files or execute arbitrary code. These critical bugs are tracked as CVE-2019-3464 and CVE-2019-3463 and feature a CVSS score of 9.8.
