AI-suggested

European organizations should immediately verify their FreeScout version and upgrade to version 1.8.180 or later to apply the official patch addressing this vulnerability. In addition to patching, organizations should audit existing user accounts and invitation workflows to detect any unauthorized activations or suspicious activity. Implementing stricter controls on invitation issuance and monitoring invitation link usage can help detect exploitation attempts. It is also advisable to enforce multi-factor authentication (MFA) on user accounts to reduce the risk of unauthorized access even if an account is improperly activated. Network segmentation of help desk systems and limiting access to invitation links via email security controls can further reduce exposure. Regularly reviewing logs for unusual account activation patterns and integrating alerts for such events will enhance detection capabilities. Finally, organizations should educate their staff about the risks of invitation link misuse and ensure secure handling of email invitations.

Description

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.180, an attacker with an unactivated email invitation containing invite_hash, can exploit this vulnerability to self-activate their account, despite it being blocked or deleted, by leveraging the invitation link from the email to gain initial access to the account. This issue has been patched in version 1.8.180.
