What to do
No fix will be released: the affected product is end of life. Replace it, or isolate it from untrusted networks until you can.
AI-suggested
Given the lack of vendor patches, European organizations should implement the following specific mitigations: 1) Immediately isolate affected Ion Torrent OneTouch 2 devices from public and untrusted networks by placing them behind strict firewall rules or within dedicated VLANs with limited access. 2) Employ network segmentation to restrict SSH access exclusively to authorized administrators and trusted management stations. 3) If possible, change the root password from the default 'ionadmin' to a strong, unique password, though this may be limited by device capabilities. 4) Monitor network traffic for unauthorized SSH login attempts targeting these devices and implement intrusion detection/prevention systems tuned for such activity. 5) Plan for phased replacement or upgrade of unsupported devices with newer, supported models that enforce secure authentication and password policies. 6) Conduct regular security audits and vulnerability assessments focused on legacy medical and research equipment. 7) Educate staff about the risks associated with legacy devices and enforce strict operational security around their use. 8) Where feasible, restrict physical and network access to these devices to minimize exposure.
Description
An issue was discovered on Thermo Fisher Ion Torrent OneTouch 2 INS1005527 devices. They run an SSH server accessible over the default port 22. The root account has a weak default password of ionadmin, and a password change policy for the root account is not enforced. Thus, an attacker with network connectivity can achieve root code execution. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
