According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.57. It is, therefore, affected by multiple vulnerabilities :
A flaw exists with the Drupal.checkPlain() function due to improper handling of HTML injection. A remote attacker, with a specially crafted request, could potentially execute arbitrary script code within the trust relationship between the browser and server. (CVE-2017-6927)
A flaw exists with the private file system due to improper checking of permissions when modules provided conflicting access. A remote attacker could potentially access sensitive files. (CVE-2017-6928)
A flaw exists with the bundled jQuery due to improper handling of Ajax requests. A remote attacker, with a specially crafted request, could potentially execute arbitrary script code within the trust relationship between the browser and server. (CVE-2017-6929)
A flaw exists with the language switcher block due to improper validation of user input. A context-dependent attacker, with a specially crafted link, could redirect a user to a malicious site.
(CVE-2017-6932)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
