Description

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
