Drupal core 7.x versions before 7.57 has an external link injection vulnerability when the language switcher block is used. A similar vulnerability exists in various custom and contributed modules. This vulnerability could allow an attacker to trick users into unwillingly navigating to an external site.

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.
