Descriptions

In osTicket before 1.12, XSS exists via /upload/file.php, /upload/scp/users.php?do=import-users, and /upload/scp/ajax.php/users/import if an agent manager user uploads a crafted .csv file to the User Importer, because file contents can appear in an error message. The XSS can lead to local file inclusion.

En osTicket versiones anteriores a 1.12, tiene una vulnerabilidad de Cross-Site Scripting (XSS) a través de /upload/file.php, /upload/scp/users.php?do=import-users, y /upload/scp/ajax.php/users/import si un usuario del gestor de agentes sube un archivo.csv creado al User Importer, en el contenido del archivo puede aparecer un mensaje de error. El XSS puede conducir a la inclusión de archivos locales.
