CVE-2023-53958Public exploitNetwork attack vector

Account takeover via poisoned password-reset link

Published Dec 19, 2025 · Updated Dec 19, 2025

Password reset poisoning in LDAP Tool Box Self Service Password 1.5.2 allows remote attackers to take over LDAP accounts via a crafted Host header. In sendtoken.php, the mail-reset path builds the reset link from the untrusted HTTP Host header when reset_url lacks a static value. Exploitation requires mail-based reset to be enabled and the victim to follow the poisoned link, which sends the valid reset token to the attacker-controlled host for password replacement.
