Cyber Security

i-SENS Inc. is a South Korea-based company that maintains offices in several countries around the world, including the United States, China, Germany, Peru, India, and Chile.

The affected product, SmartLog Diabetes Management Software, is software for patients to track and monitor personal blood glucose levels by connecting their blood glucose meters via USB to a computer. SmartLog Diabetes Management Software sees action across the healthcare and public health sector. These products end up distributed and used on a global basis.

An uncontrolled search path element vulnerability has been identified that could end up exploited by placing a specially crafted DLL file in the search path. If the malicious DLL is loaded prior to the valid DLL, an attacker could execute arbitrary code on the system. This vulnerability does not affect the connected blood glucose monitor and would not impact delivery of therapy to the patient.

CVE-2017-13993 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.3.

This vulnerability is not exploitable remotely and cannot be exploited without user interaction. The exploit only triggers when a local user runs the vulnerable application and loads the specially crafted, malicious DLL file.

No known public exploits specifically target this vulnerability. However, an attacker with a low skill level could exploit this vulnerability.

i-SENS produced an update for the SmartLog Diabetes Management Software, Version 2.4.1, which released to the i-SENS website on September 1.
