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. 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.
CVE-2018-18978
An issue was discovered in the Ascensia Contour NEXT ONE application for Android before 2019-01-15. It has a statically coded encryption key. Extraction of the encryption key 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.
CVE-2018-18977
An issue was discovered in the Ascensia Contour NEXT ONE application for Android before 2019-01-15. An attacker may reverse engineer the codebase to extract sensitive data that contributes to the disclosure of medical information of patients utilizing the Ascensia platform. This occurs because of weak obfuscation.
CVE-2018-18976
An issue was discovered in the Ascensia Contour NEXT ONE application for iOS and Android before 2019-01-15. An attacker may retrieve encrypted medical information of any user of the Ascensia cloud platform by performing Direct Object References with a series of user ID values. (This information can be decrypted through a different vulnerability.)
CVE-2018-18975
An issue was discovered in the Ascensia Contour NEXT ONE app for iOS before 2019-01-15. An attacker may proxy communications between the app and Ascensia backend servers because of a weak certificate-pinning implementation, leading to disclosure of medical information.
