What is a Password Reset Poisoning Attack?

Password Reset Poisoning Attacks — Common Examples

Basic Password Reset Poisoning Attack

  • The malicious user obtains a legitimate user’s username or email address and submits a password reset request on their behalf.
  • Hackers interject the HTTP request and modify the host header to point towards a malicious attacker-controlled domain, such as
  • The site sends a reset password email to the legitimate user, which contains a password reset link and a valid password reset token. The domain name in the token’s URL points to the attacker-controlled host, such as
  • If the victim clicks this link, a password reset token is sent to the hacker’s host.
  • The attacker visits the vulnerable application/web server and uses the relevant query parameter to submit the password token. The attacker can then reset the user’s password to their chosen value and take over the registered user’s account.
