Security readout for executives and security teams
Plain-English summary
Some Hospira infusion pumps stored wireless network keys in plain text. In a healthcare environment, this can turn a device-management weakness into a network access concern. The source bundle does not provide a CVSS score or evidence of active exploitation.
Executive priority
Treat this as a healthcare device hygiene issue with network security implications. Prioritize inventory and port closure for affected pumps, then confirm vendor-supported remediation or replacement options.
Technical view
CVE-2015-3952 is a CWE-312 cleartext storage issue affecting Hospira Plum A+ <=13.4, Plum A+3 <=13.6, and Symbiq <=3.13. Hospira recommended closing FTP Port 20 and TELNET Port 23 on affected devices. Plum 360 is stated as not vulnerable.
Likely exposure
Exposure is most likely in healthcare environments still operating the named Hospira infusion systems at or below the affected versions, especially where device FTP or Telnet access remains reachable on clinical or wireless networks.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. They indicate stored wireless keys are exposed in plain text, but do not describe required access level, exploit maturity, or observed attacks.
Researcher notes
The bundle supports cleartext wireless key storage and specific affected versions, but lacks CVSS details, patch identifiers, exploit prerequisites, and exploitation evidence. Avoid assuming remote exploitation beyond the cited FTP/Telnet mitigation guidance.
Mitigation direction
- Close Port 20/FTP on affected devices as Hospira recommended.
- Close Port 23/TELNET on affected devices as Hospira recommended.
- Identify whether any affected models remain in service.
- Check Hospira or successor vendor guidance for supported remediation options.
- Consider Plum 360 status when evaluating replacement options.
Validation and detection
- Inventory Plum A+, Plum A+3, and Symbiq devices by model and version.
- Confirm Plum A+ devices are above version 13.4 or remediated.
- Confirm Plum A+3 devices are above version 13.6 or remediated.
- Confirm Symbiq devices are above version 3.13 or remediated.
- Verify network controls block FTP and Telnet access to affected devices.

Cleartext Storage of Sensitive Information
Cleartext Storage of Sensitive Information represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
