CVE-2018-18979

An issue was discovered in the Ascensia Contour NEXT ONE application for Android before 2019-01-15. It has a statically coded initialization vector.

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.
