CVE-2024-3777Network attack vector

Account takeover via unauthenticated password reset

Published Apr 15, 2024 · Updated Oct 14, 2024

Missing authentication in Ai3 QbiBot 8.0.4 and earlier allows remote attackers to reset any user's password over the network. The password-reset feature processes a target user's reset request and changes the account password without first authenticating the requester. Anyone who can reach the service can take over another user's account by assigning a new password, with no credentials or user interaction required.
