CVE-2020-11967

CRITICAL

IQrouter Firmware < 3.3.1 - Unauthenticated Remote Device Control via Missing Authorization

Title source: llm
STIX 2.1

Description

In IQrouter through 3.3.1, remote attackers can control the device (restart network, reboot, upgrade, reset) because of Incorrect Access Control. Note: The vendor claims that this vulnerability can only occur on a brand-new network that, after initiating the forced initial configuration (which has a required step for setting a secure password on the system), makes this CVE invalid. This vulnerability is “true for any unconfigured release of OpenWRT, and true of many other new Linux distros prior to being configured for the first time”
