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 in Roche Accu-Chek Inform II Instrument before 03.06.00 (Serial number below 14000) and 04.x before 04.03.00 (Serial Number above 14000), CoaguChek Pro II before 04.03.00, CoaguChek XS Plus before 03.01.06, CoaguChek XS Pro before 03.01.06, cobas h 232 before 03.01.03 (Serial number below KQ0400000 or KS0400000), and cobas h 232 before 04.00.04 (Serial number above KQ0400000 or KS0400000). A vulnerability in the software update mechanism allows authenticated attackers in the adjacent network to overwrite arbitrary files on the system through a crafted update package.

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

The vulnerability exists in the software update mechanism of multiple Roche medical devices (Accu-Chek Inform II, CoaguChek Pro II, CoaguChek XS Plus, CoaguChek XS Pro, and cobas h 232). Authenticated attackers on the adjacent network can exploit this flaw by crafting malicious update packages that allow arbitrary file overwrite on the targeted system, potentially enabling code execution or system compromise.

MitigationApply the vendor-supplied patches by updating to the fixed software versions (Accu-Chek Inform II 03.06.00 or 04.03.00, CoaguChek Pro II 04.03.00, CoaguChek XS Plus/XS Pro 03.01.06, cobas h 232 03.01.03 or 04.00.04 depending on serial number). Additionally, implement network segmentation to restrict access to the adjacent network and enforce authentication controls for update mechanisms.

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 the Roche device model
    Locate the device label or access the device's system information to confirm whether it is an Accu-Chek Inform II, CoaguChek Pro II, CoaguChek XS Plus, CoaguChek XS Pro, or cobas h 232 unit
    Affected if The device matches one of the affected product lines listed in the CVE
  2. Check the installed firmware version
    Access the device's built-in system settings, maintenance menu, or diagnostic screen to view the current firmware version. Compare it against the affected version ranges: Accu-Chek Inform II < 03.06.00 or >= 04.00.00 and < 04.03.00; cobas h 232 < 03.01.03 or >= 04.00.00 and < 04.00.04; CoaguChek Pro II < 04.03.00; CoaguChek XS Plus < 03.01.06; CoaguChek XS Pro < 03.01.06
    Affected if The installed firmware version falls within any of the vulnerable ranges listed in the CVE
  3. Verify network accessibility to the device
    Determine whether the device is connected to a network segment that allows adjacent network attackers to reach the device's software update interface
    Affected if The device's update mechanism is reachable from an adjacent network without additional network segmentation or firewall controls
  4. Check update mechanism configuration
    Review the device settings or documentation to determine whether the software update mechanism is configured to accept packages without requiring strong authentication
    Affected if The update mechanism does not enforce authentication or uses weak credentials for update package validation

A defender is affected if their Roche device matches one of the listed models and runs firmware versions below the fixed thresholds while the software update mechanism is accessible from an adjacent network without proper authentication controls.

Interim mitigation

Apply the vendor-supplied patches by updating to the fixed software versions (Accu-Chek Inform II 03.06.00 or 04.03.00, CoaguChek Pro II 04.03.00, CoaguChek XS Plus/XS Pro 03.01.06, cobas h 232 03.01.03 or 04.00.04 depending on serial number).
