CVE-2022-33011Public exploitNetwork attack vector

Account takeover via poisoned password-reset link

Published Jul 8, 2022 · Updated Aug 3, 2024

Host header injection in idno Known 1.3.1 and earlier allows remote attackers to take over accounts through password-reset links. The password-reset flow uses the untrusted HTTP Host header to build the emailed reset URL, so a crafted request points the victim's reset token at an attacker-controlled host. Exploitation requires the victim to follow the poisoned link, which discloses the token and lets the unauthenticated requester reset that account's password.
