Independent researcher Mark Cross has identified an uncontrolled search path element vulnerability in i-SENS, Inc. SmartLog Diabetes Management Software. i-SENS has produced an update that mitigates this vulnerability. Mark Cross has tested the update to validate that it resolves the vulnerability.


The following SmartLog Diabetes Management Software versions are affected:

  • SmartLog Diabetes Management Software, Version 2.4.0 and prior versions.


Exploitation of this vulnerability could allow an authorized local attacker to execute arbitrary code on the target system.


i-SENS 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. According to i-SENS, SmartLog Diabetes Management Software is deployed across the Healthcare and Public Health sector. i-SENS estimates that these products are distributed and used worldwide.




An uncontrolled search path element vulnerability has been identified which could be 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-2017-13993b has been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been assigned; the CVSS vector string is (AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H).c



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


No known public exploits specifically target this vulnerability.


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 was released to the i-SENS website on September 1, 2017. It can be found at the following location:
