CVE-2021-25102Public exploitNetwork attack vector

Reflected script execution via raw redirect_to

Published May 2, 2022 · Updated Aug 3, 2024

Reflected XSS in TeamUpdraft All-In-One Security before 4.4.11 allows remote attackers to run script through redirect_to. The renamed-login handler passes redirect_to without validation, sanitization, or escaping into a Location header or meta URL attribute. The Rename Login Page feature must be active, its custom URL must be known, and a logged-in user must load the crafted URL; the same input can also cause an external redirect.
