CVE-2024-34077: Mantis Bug Tracker (MantisBT) allows user account takeover in the signup/reset password process

Insufficient access control in the registration and password reset process allows an attacker to reset another user’s password and takeover their account, if the victim has an incomplete request pending.

The exploit is only possible while the verification token is valid, i.e for 5 minutes after the confirmation URL sent by e-mail has been opened, and the user did not complete the process by updating their password.

A brute-force attack calling account_update.php with increasing user IDs is possible.
