VAR-202101-1833

Vulnerability from variot - Updated: 2024-05-17 23:09

Home Assistant before 2021.1.3 does not have a protection layer that can help to prevent directory-traversal attacks against custom integrations. NOTE: the vendor's perspective is that the vulnerability itself is in custom integrations written by third parties, not in Home Assistant; however, Home Assistant does have a security update that is worthwhile in addressing this situation. Home Assistant is an open source home automation management system. The system is mainly used to control home automation equipment.

There is a directory traversal vulnerability before Home Assistant 2021.1.3 version. The vulnerability stems from failure to properly filter special elements in resource or file paths. Attackers can use this vulnerability to obtain directory information
