The self-reported SGOS version installed on the remote Symantec ProxySG device is 6.5.x prior to 6.5.10.15 or 6.6.x prior to 6.7.4.2. It is, therefore, affected by the following vulnerabilities:
A cross-site scripting (XSS) vulnerability in ProxySG FTP proxy WebFTP mode.
An authenticated, remote attacker can exploit this, by injecting malicious JavaScript code in ProxySG’s web listing of a remote FTP server. (CVE-2018-18370)
An information disclosure vulnerability exists in ProxySG FTP proxy WebFTP mode.
An authenticated, remote attacker can exploit this, via intercepting FTP connections where a user accesses an FTP server, to obtain plaintext authentication credentials. (CVE-2018-18371)
