      "value": "The ASG/ProxySG FTP proxy WebFTP mode allows intercepting FTP connections where a user accesses an FTP server via a ftp:// URL in a web browser. A stored cross-site scripting (XSS) vulnerability in the WebFTP mode allows a remote attacker to inject malicious JavaScript code in ASG/ProxySG's web listing of a remote FTP server. Exploiting the vulnerability requires the attacker to be able to upload crafted files to the remote FTP server. Affected versions: ASG 6.6 and 6.7 prior to 6.7.4.2; ProxySG 6.5 prior to 6.5.10.15, 6.6, and 6.7 prior to 6.7.4.2."

Una vulnerabilidad de tipo cross-site scripting (XSS) almacenado en el modo WebFTP permite a un atacante remoto inyectar código JavaScript malicioso en un listado web de ASG/ProxySG de un servidor FTP remoto. La explotación de la vulnerabilidad requiere que el atacante sea capaz de cargar archivos  especialmente diseñados en el servidor FTP remoto. Versiones afectadas: ASG versión 6.6 y versiones 6.7 anteriores a 6.7.4.2; ProxySG versiones 6.5 anteriores a 6.5.10.15, 6.6 y versiones 6.7 anteriores a 6.7.4.2."
