Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-640: Weak Password Recovery Mechanism for Forgotten Password, where the product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak. In Craftcms/cms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Craft CMS through 3.7.36 allows a remote unauthenticated attacker, who knows at least one valid username, to reset the account's password and take over the account by providing a crafted HTTP header to the application while using the password reset functionality. Specifically, the attacker must send X-Forwarded-Host to the /index.php?p=admin/actions/users/send-password-reset-email URI. NOTE: the vendor's position is that a customer can already work around this by adjusting the configuration (i.e., by not using the default configuration).
