Description

This security bulletin contains information about 1 vulnerability.


1) Improper access control (CVE-ID: CVE-2020-12030)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to a flaw in the code used to configure the internal gateway firewall when the gateway's VLAN feature is enabled. If a user enables the VLAN setting, the internal gateway firewall becomes disabled resulting in exposure of all ports used by the gateway. A remote attacker can issue specific commands to the gateway, which could then be forwarded on to the end user's wireless devices.
