CyberRota Analysis

AI-Generated

Wallos versions 2.0.0 to before 5.0.0 are vulnerable to Server-Side Request Forgery (SSRF), allowing any authenticated user to configure the server to establish outbound SMTP connections to internal IP addresses. This could lead to unauthorized access to internal services or data leakage. Organizations using Wallos for subscription tracking should prioritize upgrading to version 5.0.0 to mitigate this risk.

Original NVD Description

Wallos is an open-source, self-hostable personal subscription tracker. From version 2.0.0 to before version 5.0.0, any authenticated Wallos user (no admin rights required) can make the server open arbitrary outbound SMTP connections to internal/link-local addresses, by setting the SMTP host of their personal email notifications to an internal IP. The per-user notification settings endpoint (endpoints/notifications/saveemailnotifications.php) performs no SSRF validation, and the notification cron (endpoints/cronjobs/sendnotifications.php) feeds that user-controlled host straight into PHPMailer ($mail->Host = $email['smtpAddress']). When the user's subscription notification fires, the server connects to the chosen host:port. This issue has been patched in version 5.0.0.
