MEDIUM NUCLEI

Home Assistant < 2021.1.3 - Path Traversal in Custom Integrations

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2021-3152 has a Nuclei detection template available — see the Nuclei card below for the Shodan/FOFA recon queries.

Description

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
