Phishing redirects via unvalidated destination parameter
Published Jun 17, 2022 · Updated Aug 3, 2024
Open redirect in u5cms 8.3.5 allows remote attackers to redirect a user's browser through a crafted /loginsave.php URL. The endpoint accepts the u query parameter as an external destination and returns an HTTP 302 Location header without restricting it to the u5cms site. Exploitation requires a user to open an attacker-constructed link; the resulting trusted-domain redirect can deliver the browser to a phishing site.
