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 application does not properly validate user input in the '/edit_command?sid=' endpoint, specifically in the 'source_dir' and 'dest_dir' parameters. An attacker can exploit this by sending malicious content to an authenticated user, which then gets stored and executed in the user's browser.
How can this vulnerability impact me? :
This vulnerability can allow an attacker to steal information from an authenticated user's session by injecting malicious scripts. This can lead to unauthorized access to sensitive data, session hijacking, or other malicious actions performed on behalf of the user.
