AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a persistent authenticated Cross-Site Scripting (XSS) issue in Sync Breeze Enterprise Server v10.4.18 and Disk Pulse Enterprise v10.4.18. It occurs because the software does not properly validate user input in the '/server_options?sid=' endpoint, specifically in parameters like 'tasks_logs_dir', 'errors_logs_dir', 'error_notifications_address', 'status_notifications_address', and 'status_reports_address'. An attacker who is authenticated can send malicious content that gets stored and later executed in the context of another authenticated user's session.
How can this vulnerability impact me? :
This vulnerability can allow an attacker to steal information from the session of an authenticated user by injecting malicious scripts. This could lead to unauthorized access to sensitive data, session hijacking, or other malicious actions performed on behalf of the user.
