Independent researcher Billy Rios has identified four vulnerabilities in Hospira’s MedNet server software. Hospira has released a new version of the MedNet software and provided mitigation recommendations that mitigate the reported vulnerabilities.
Three of the four vulnerabilities could be exploited remotely.
The following MedNet software versions are affected:
Exploitation of these vulnerabilities may allow an attacker to remotely compromise MedNet servers and push unauthorized modifications to medication libraries and pump configurations.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/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 MedNet server software manages drug libraries, firmware updates, and configurations of Hospira intravenous pumps. The affected products are deployed across the Healthcare and Public Health Sector. Hospira estimates that these products are used worldwide.
The MedNet software uses hard-coded cryptographic keys that could enable an attacker to intercept encrypted traffic from infusion pumps.
CVE-2014-5403NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-5403, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v2 base score of 6.8 has been assigned; the CVSS vector string is (AV:N/AC:L/Au:S/C:C/I:N/A:N).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:L/Au:S/C:C/I:N/A:N, web site last accessed March 31, 2015.
The MedNet software contains plaintext storage of passwords for the SQL database that may allow an attacker to compromise the MedNet SQL server and gain administrative access to the workstation.
CVE-2014-5405NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-5405, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v2 base score of 9.0 has been assigned; the CVSS vector string is (AV:N/AC:L/Au:S/C:C/I:C/A:C).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:L/Au:S/C:C/I:C/A:C, web site last accessed March 31, 2015.
The MedNet software stores clear text usernames and passwords on the local file system that were used during the installation process that may allow a malicious user to compromise the MedNet installation.
CVE-2014-5400NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-5400, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v2 base score of 6.8 has been assigned; the CVSS vector string is (AV:L/AC:L/Au:S/C:C/I:C/A:C).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:L/AC:L/Au:S/C:C/I:C/A:C, web site last accessed March 31, 2015.
The MedNet software uses vulnerable versions of the JBoss Enterprise Application Platform software that may allow unauthenticated users to execute arbitrary code on the target system.
CVE-2014-5401NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-5401, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v2 base score of 10.0 has been assigned; the CVSS vector string is (AV:N/AC:L/Au:N/C:C/I:C/A:C).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:L/Au:N/C:C/I:C/A:C, web site last accessed March 31, 2015.
Three of the four vulnerabilities could be exploited remotely. The Password in Configuration File vulnerability is locally exploitable.
No known public exploits specifically target these vulnerabilities.
An attacker with a low skill would be able to exploit these vulnerabilities.
Hospira has developed a new version of the MedNet software, MedNet 6.1. Hospira reports that MedNet 6.1 no longer uses hard-coded passwords, hard-coded cryptographic keys, and no longer stores passwords in clear text. Existing versions of MedNet can be upgraded to MedNet 6.1.
Hospira has produced mitigation recommendations that help mitigate the vulnerability in the vulnerable version of JBoss Enterprise Application Platform software, used in the MedNet software. This has been addressed by Hospira through issuance of the following knowledge based articles: Improving Security in Hospira MedNet 5.5 (August 2014) and Improving Security in Hospira MedNet 5.8 (August 2014). For additional information about Hospira’s new releases and mitigation recommendations, contact Hospira’s technical support at 1-800-241-4002.
ICS-CERT encourages asset owners to take additional defensive measures to protect against this and other cybersecurity risks.
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 (http://ics-cert.us-cert.gov/).
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.
