EUVDB-ID: #VU28288

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-1798

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a local user to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests when handling NFC work. An authenticated attacker with physical access can establish a NFC connection to the target phone and perform a series of operations on the target phone, which is beyond the guest user's privilege.

Mitigation

Install updates from vendor's website.
