Hospira LifeCare PCA Infusion System Vulnerabilities

Independent researcher Billy Rios has identified an improper authorization 
vulnerability and an insufficient verification of data authenticity 
vulnerability in Hospiras LifeCare PCA Infusion System, which NCCIC/ICS-CERT 
has been coordinating with Hospira since May 2014. This advisory is being 
issued to provide notice of public disclosures of the identified 
vulnerabilities in the LifeCare PCA Infusion System. Hospira has developed a 
new version that mitigates these vulnerabilities, which is undergoing U.S. 
Food and Drug Administration (FDA) review. The release date for the new 
version has not been determined.

These vulnerabilities could be exploited remotely.


The following Hospira products are affected:

LifeCare PCA Infusion System, Version 5.0 and prior versions.


Exploitation of the improper authorization vulnerability may allow 
unauthenticated users to access the LifeCare PCA Infusion pump with root 
privileges by default. Exploitation of the insufficient verification of data 
authenticity vulnerability may allow an attacker to remotely push unauthorized
modifications to the LifeCare PCA Infusion pump impacting medication libraries
and pump configuration. While drug libraries, software updates, and pump 
configurations can be modified, according to Hospira, it is not possible to 
remotely operate the LifeCare PCA Infusion pump. Operation of the LifeCare PCA
Infusion pump requires a clinician to be present at the pump to manually 
program the pump with a specified dosage before medication can be 

Impact to individual organizations depends on many factors that are unique to
each organization. ICS-CERT recommends that organizations evaluate the impact
of these vulnerabilities based on their operational environment, architecture,
and product implementation.


Hospira is a US-based company that maintains offices in several countries 
around the world.

The affected product, the LifeCare PCA Infusion System, is an intravenous pump
that delivers medication to patients. The affected products are deployed 
across the Healthcare and Public Health Sector. Hospira estimates that these 
products are used worldwide.




The LifeCare PCA Infusion pumps communication module gives unauthenticated 
users root privileges on Port 23/TELNET by default. An unauthorized user may 
be able to issue commands to modify the configuration of the pump.

CVE-2015-3459[b] has been assigned to this vulnerability. A CVSS v2 base score 
of 10.0 has been assigned; the CVSS vector string is 


The LifeCare PCA Infusion pump could have drug libraries, software updates, 
and configuration changes uploaded to it from an unauthorized source. The 
LifeCare PCA Infusion pump listens on the following ports: Port 23/TELNET, 
Port 80/HTTP, Port 443/HTTPS, and Port 5000/UPNP.

CVE-2014-5406[e] has been assigned to this vulnerability. A CVSS v2 base score 
of 7.6 has been assigned; the CVSS vector string is 



These vulnerabilities could be exploited remotely.


No known public exploits specifically target these vulnerabilities.


An attacker with low skill would be able to exploit one of these 
vulnerabilities; the other vulnerability would require high skill to exploit.


ICS-CERT has been working with Hospira since May 2014 to address the 
vulnerabilities in the LifeCare PCA Infusion System. Hospira has developed a 
new version of the PCS Infusion System, Version 7.0 that addresses the 
identified vulnerabilities. According to Hospira, Version 7.0 has Port 20/FTP
and Port 23/TELNET closed by default to prevent unauthorized access. Existing
PCA Infusion Systems running Version 5.0 can be upgraded to Version 7.0 when 
it becomes available. Hospiras Version 7.0 is being reviewed by the FDA prior
to its release. The release date for Version 7.0 of the LifeCare PCA Infusion
System has not been determined.

For additional information about Hospiras new release, contact Hospiras 
technical support at 1-800-241-4002.

ICS-CERT encourages asset owners to take defensive measures to protect against
this and other cybersecurity risks.

Ensure that unused ports are closed, to include Port 20/FTP and Port 

Maintain layered physical and logical security to implement defense-in-depth 
security practices for environments operating medical devices.

Isolate the LifeCare PCA Infusion pump from the Internet and untrusted 
systems; however, if connectivity is required, use a Virtual Private Network 
(VPN) solution and implement network monitoring.

When remote access is required, use secure methods, such as VPNs, recognizing
that VPNs may have vulnerabilities and should be updated to the most current 
version available. Also recognize that VPN is only as secure as the connected

Produce an MD5 checksum of key files to identify any unauthorized changes.

Use good design practices that include network segmentation. Use DMZs with 
properly configured firewalls to selectively control traffic and monitor 
traffic passed between zones and systems to identify anomalous activity. Use 
the static nature of these isolated environments to look for anomalous 

ICS-CERT also provides a section for security recommended practices on the 
ICS-CERT web page at: 
http://ics-cert.us-cert.gov/content/recommended-practices. ICS-CERT reminds 
organizations to perform proper impact analysis and risk assessment prior to 
deploying defensive measures.

Additional mitigation guidance and recommended practices are publicly 
available in the ICS-CERT Technical Information Paper, 
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation 
Strategies, that is available for download from the ICS-CERT web site 

Organizations observing any suspected malicious activity should follow their 
established internal procedures and report their findings to ICS-CERT for 
tracking and correlation against other incidents.
