CVE-2018-18978

Exp

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.

7.4 3.0 HIGH
CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
