Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3


The remote host is running a web application that is affected by a reflected cross-site scripting vulnerability.


According to its self-reported version number, the Sophos Web Appliance software running on the remote host is prior to 4.3.2. It is, therefore, affected by a reflected cross-site scripting (XSS) vulnerability in the FTP redirect page (ftp_redirect.php) due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.


Upgrade to Sophos Web Appliance version 4.3.2 or later.
