Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU53154

Risk: Low

CVSSv3.1: 4.9 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2020-24586

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in the 802.11 standard due to the affected device does not clear its cache/memory to remove fragments of an incomplete MSDU/MMPDU from previous session after reconnection/reassociation. A remote attacker on the local network can perform a fragment cache attack and perform a denial of service (DoS) attack.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
