SCA: security update for homeassistant (GHSA-qhhj-7hrc-gqj5)
medium Tenable Self-Hosted Container Security Plugin ID 418147
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Home assistant is an open source home automation. The audit team’s analyses confirmed that the
`redirect_uri` and `client_id` are alterable when logging in. Consequently, the code parameter utilized to
fetch the `access_token` post-authentication will be sent to the URL specified in the aforementioned
parameters. Since an arbitrary URL is permitted and `homeassistant.local` represents the preferred,
default domain likely used and trusted by many users, an attacker could leverage this weakness to
manipulate a user and retrieve account access. Notably, this attack strategy is plausible if the victim
has exposed their Home Assistant to the Internet, since after acquiring the victim’s `access_token` the
adversary would need to utilize it directly towards the instance to achieve any pertinent malicious
actions. To achieve this compromise attempt, the attacker must send a link with a `redirect_uri` that they
control to the victim’s own Home Assistant instance. In the eventuality the victim authenticates via said
link, the attacker would obtain code sent to the specified URL in `redirect_uri`, which can then be
leveraged to fetch an `access_token`. Pertinently, an attacker could increase the efficacy of this
strategy by registering a near identical domain to `homeassistant.local`, which at first glance may appear
legitimate and thereby obfuscate any malicious intentions. This issue has been addressed in version
2023.9.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
