Summary
An issue was discovered in the Ascensia Contour NEXT ONE application for Android before 2019-01-15. It has a statically coded initialization vector. Extraction of the initialization vector is necessary for deciphering communications between this application and the backend server. This, in combination with retrieving any user's encrypted data from the Ascensia cloud through another vulnerability, allows an attacker to obtain and modify any patient's medical information.
Patch / fix
- ascensia contour_diabetes 2.5.0
Exploit prediction
1.17% chance of exploitation in the next 30 days, higher than 67% of all scored CVEs (FIRST EPSS, 2026-11-08).
