Password changes via unverified cross-origin profile request
Published Jul 6, 2022 · Updated Aug 3, 2024
Cross-site request forgery in PESCMS 2.3.3 allows remote attackers to change administrator and member passwords through a crafted form. The App/Team/PUT/User.php settings handler accepts a cross-origin POST and updates profile fields without verifying that the authenticated user intended the request. Exploitation requires a logged-in administrator or member to submit the attacker's form, allowing password, email, phone, and profile-image changes within that victim's privileges.
