STIX 2.1

Description

An issue was discovered in Heimdal Thor agent versions 3.4.2 and before 3.7.0 on Windows, allows attackers to bypass USB access restrictions, execute arbitrary code, and obtain sensitive information via Next-Gen Antivirus component. NOTE: Heimdal argues that the limitation described here is a Microsoft Windows issue, not a Heimdal specific vulnerability. The USB control solution by Heimdal is meant to manage Microsoft Windows native USB restrictions. They maintain that their solution functions as a management layer over Windows settings and is not to blame for limitations in Windows' detection capabilities.
