CVE-2018-18371

Estado: ModificadaMedia (6.5)—

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. An information disclosure vulnerability in the WebFTP mode allows a malicious user to obtain plaintext authentication credentials for a remote FTP server from the ASG/ProxySG's web listing of the 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.
