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 unauthenticated remote attacker may be able to execute commands to view wireless account credentials that are stored in cleartext on Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module (WBM) version 16, which may allow an attacker to gain access the host network. Baxter has released a new version of the SIGMA Spectrum Infusion System, Version 8, which incorporates hardware and software changes.

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 Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module version 16 contains an unauthenticated remote command injection vulnerability that allows attackers to view wireless account credentials stored in cleartext, potentially enabling access to the host hospital network.

MitigationUpgrade to Baxter SIGMA Spectrum Infusion System Version 8, which includes both hardware and software changes to address this vulnerability. Until upgraded, network segmentation should be applied to isolate infusion pumps from critical network segments.

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 Baxter Sigma Spectrum model number
    Locate the model label on the infusion pump physical device or in the device management interface; confirm it is model 35700BAX
    Affected if Model number is 35700BAX (proceed to version check)
  2. Check the installed firmware version
    Access the pump's system information menu or maintenance interface; record the firmware version displayed
    Affected if Firmware version is exactly 6.05 (this version is listed as affected)
  3. Check the wireless battery module version
    Access the wireless settings or battery module information screen on the device; note the wireless battery module version number
    Affected if Wireless battery module version is 16 (this specific version is listed as vulnerable)
  4. Verify wireless functionality is enabled
    Check the device network settings to confirm wireless communication is turned on and configured
    Affected if Wireless is enabled and configured (the vulnerability exposes wireless credentials)

A user is affected if their Baxter Sigma Spectrum Infusion System is model 35700BAX with firmware version 6.05 and wireless battery module version 16, with wireless functionality enabled.

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

Upgrade to Baxter SIGMA Spectrum Infusion System Version 8, which includes both hardware and software changes to address this vulnerability. Until upgraded, network segmentation should be applied to isolate infusion pumps from critical network segments.

Recommended fix High confidence

Sigma Spectrum Infusion System Version 8

  1. Verify current firmware version by accessing the Sigma Spectrum Infusion System administration interface or checking the device label (model 35700BAX, WBM version 16)
  2. Contact Baxter technical support to obtain the Version 8 firmware upgrade for the Sigma Spectrum Infusion System
  3. Schedule a maintenance window as the upgrade may require system downtime
  4. Follow Baxter's official upgrade procedure to install Version 8 firmware, which includes both hardware and software changes
  5. After upgrade, verify the system is running Version 8 and confirm wireless credentials are no longer stored in cleartext
  6. Test wireless connectivity and infusion system functionality to ensure proper operation
Caveat Version 8 incorporates hardware changes in addition to software fixes; ensure compatibility with existing infrastructure and consult Baxter for integration requirements
