To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of Agent.\r\n\r\nThis vulnerability is due to inadequate validation of file contents during file upload operations. An attacker could exploit this vulnerability by uploading a file that contains malicious scripts or HTML code, which the application could make available to other users to access. A successful exploit could allow the attacker to execute the contents of that file in the browser of a user and conduct browser-based attacks. "
