User redirection via unchecked redirect parameter
Published Apr 27, 2021 · Updated Aug 4, 2024
Open redirect in HomeAutomation 3.3.2 allows remote attackers to redirect users to arbitrary websites through a crafted api.php link. In api.php, the redirect GET parameter is passed to redirectTo(), which inserts the supplied value directly into the HTTP Location header without validating the destination. Exploitation requires a user to follow the crafted trusted-domain link; the resulting redirect sends the browser to an attacker-chosen site.
