Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU53161

Risk: Low

CVSSv3.1: 5 [CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-26140

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. A remote attacker on the local network can inject arbitrary data frames independent of the network configuration.

Mitigation

Install updates from vendor's repository.
