CVE-2024-23648Public exploitNetwork attack vector

Account takeover via Host-derived password-reset links

Published Jan 24, 2024 · Updated Jun 17, 2025

Host header injection in Pimcore Admin UI Classic Bundle before 1.2.3 allows remote attackers to take over accounts through reset links. LoginController generates an absolute password-reset URL from the request Host header and emails the resulting attacker-controlled link with a token. Exploitation requires acceptance of an arbitrary Host value and a recipient who follows the emailed link, exposing the token needed to reset that account.
