Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Improper Authentication
EUVDB-ID: #VU48954
Risk: Medium
CVSSv4.0: 5.9 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-25183
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in when processing authentication requests. A remote attacker on the local network can use another mobile device or malicious application on the patient’s smartphone to bypass authentication process and gain unauthorized access to the application.
