Detailsinfo

A vulnerability has been found in Home Assistant up to 2024.1.5 and classified as problematic. Affected by this vulnerability is an unknown code of the component SSL Certificate Handler. The manipulation with an unknown input leads to a verification of source vulnerability. The CWE definition for the vulnerability is CWE-940. The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Home Assistant Core is an open source home automation that puts local control and privacy first. Affected versions are subject to a potential man-in-the-middle attacks due to missing SSL certificate verification in the project codebase and used third-party libraries. In the past, `aiohttp-session`/`request` had the parameter `verify_ssl` to control SSL certificate verification. This was a boolean value. In `aiohttp` 3.0, this parameter was deprecated in favor of the `ssl` parameter. Only when `ssl` is set to `None` or provided with a correct configured SSL context the standard SSL certificate verification will happen. When migrating integrations in Home Assistant and libraries used by Home Assistant, in some cases the `verify_ssl` parameter value was just moved to the new `ssl` parameter. This resulted in these integrations and 3rd party libraries using `request.ssl = True`, which unintentionally turned off SSL certificate verification and opened up a man-in-the-middle attack vector. This issue has been addressed in version 2024.1.6 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
