CVE-2018-18979
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
