# Smiths-Medical CADD-Solis Medication Safety Software Vulnerabilities
#


### OVERVIEW

This advisory was originally posted to the US-CERT secure Portal library on November 1, 2016, and is being released to the NCCIC/ICS-CERT web site.
Smiths-Medical has reported two vulnerabilities in Smiths-Medicalās CADD-Solis Medication Safety Software that were identified by Andrew Gothard of Newcastle Upon Tyne Hospitals NHS Foundations Trust. Smiths-Medical has produced new versions to mitigate these vulnerabilities. Smiths-Medical reports that an independent security expert has tested the new versions to validate that they resolve the identified vulnerabilities.
These vulnerabilities could be exploited remotely.



### AFFECTED PRODUCTS

The following CADD-Solis Medication Safety Software versions are affected:
Smiths-Medical CADD-Solis Medication Safety Software, Version 1.0;
Smiths-Medical CADD-Solis Medication Safety Software, Version 2.0;
Smiths-Medical CADD-Solis Medication Safety Software, Version 3.0; and
Smiths-Medical CADD-Solis Medication Safety Software, Version 3.1



### IMPACT

Successful exploitation of these vulnerabilities may allow an authenticated user to add users, delete users, and to modify permissions via the CADD-Solis Medication Safety Software. Drug libraries can also be modified in the CADD-Solis Medication Safety Software. However, to update the drug libraries on a pump, a laptop with the CADD-Solis Medication Safety Software would have to be physically plugged into one of two different types of pumps, the CADD-Prizm System and the CADD-Solis Ambulatory Infusion Pump.
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 and specific clinical usage.



### BACKGROUND

Smiths-Medical is headquartered in Plymouth, Minnesota, and is a subsidiary of Smiths Group plc, which is a UK-based company.
The affected product, the CADD-Solis Medication Safety Software, is an application that is used to set dosage limits for infusion pumps. According to Smiths-Medical, the CADD-Solis Medication Safety Software can interface with the CADD-Prizm System and the CADD-Solis Ambulatory Infusion Pump, which are deployed across the Healthcare and Public Health sector. Smiths-Medical estimates that this product is sold worldwide.



### VULNERABILITY CHARACTERIZATION

INCORRECT PERMISSION ASSIGNMENT FOR CRITICAL RESOURCEa
CADD-Solis Medication Safety Software grants an authenticated user elevated privileges on the SQL database, which would allow an authenticated user to modify drug libraries, add and delete users, and change user permissions. According to Smiths-Medical, physical access to the pump is required to install drug library updates.
CVE-2016-8355b has been assigned to this vulnerability. A CVSS v3 base score of 9.9 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H)

MAN-IN-THE-MIDDLEd
The affected software does not verify the identities at communication endpoints, which may allow a remote attacker to gain access to the communication channel between endpoints.
CVE-2016-8358e has been assigned to this vulnerability. A CVSS v3 base score of 8.5 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H)
