Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Thermo Fisher Ion Torrent OneTouch 2 devices run an SSH server on port 22 with a weak default root password 'ionadmin' and no enforced password change policy. An attacker with network connectivity can authenticate with these default credentials and achieve root code execution, resulting in complete device compromise.

MitigationImmediately change the default root password from 'ionadmin' to a strong, unique password; disable root SSH access if possible; network-isolate the device or place it behind a firewall restricting SSH access to trusted IPs only; since the product is unsupported, consider replacement if security cannot be adequately maintained.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Ion Torrent OneTouch 2 devices on your network
    Scan your network for devices with SSH (port 22) open and examine device fingerprints, hostnames, or MAC OUIs matching Thermo Fisher Ion Torrent equipment
    Affected if A Thermo Fisher Ion Torrent OneTouch 2 device is present and has SSH port 22 accessible from your network
  2. Verify SSH service is enabled and accessible
    Attempt a TCP connection to port 22 on the device IP address to confirm the SSH service is running and responding
    Affected if The SSH service is listening and accepting connections on port 22
  3. Confirm default credentials are active
    Attempt SSH authentication to the device using username 'root' with password 'ionadmin'
    Affected if The default credentials successfully authenticate and grant root access
  4. Assess network accessibility of SSH
    Determine whether the device SSH port is exposed to untrusted networks, is behind a properly configured firewall, or is in an isolated network segment
    Affected if The device SSH port is accessible from networks that contain untrusted or internet-facing systems
  5. Check if SSH is required for operations
    Review device documentation and your operational procedures to determine whether SSH access is a necessary function for your workflow or if it can be disabled
    Affected if SSH is enabled but not required for critical operations, and the device remains vulnerable

You are affected if you have an Ion Torrent OneTouch 2 device with SSH port 22 accessible on your network where the default root password 'ionadmin' still grants access.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Immediately change the default root password from 'ionadmin' to a strong, unique password; disable root SSH access if possible; network-isolate the device or place it behind a firewall restricting SSH access to trusted IPs only; since the product is unsupported, consider replacement if security cannot be adequately maintained.

Recommended fix Moderate confidence
  1. 1. Isolate the affected Ion Torrent OneTouch 2 device on a dedicated network segment or VLAN to limit network exposure.
  2. 2. Block inbound SSH access (port 22) at network firewalls or access control lists to prevent external attackers from reaching the device.
  3. 3. If SSH access is required for legitimate purposes, implement network-level authentication mechanisms such as VPN or jump host before allowing SSH connections.
  4. 4. Change the default root password 'ionadmin' to a strong, complex password if the device's CLI permits this change.
  5. 5. Since Thermo Fisher no longer supports this product, evaluate migrating to a currently supported sequencing platform to receive security updates.
Caveat Product is End-of-Life and no longer supported by Thermo Fisher; no firmware updates or security patches are available.
