The version of Drupal running on the remote web server is 8.x prior to 8.1.10. It is, therefore, affected by multiple vulnerabilities :
A flaw exists due to improper checking for ‘Administrator comments’ permissions, which allows users who have rights to edit a node to set the visibility for comments on that node. An authenticated, remote attacker can exploit this to adjust a node’s comment visibility preferences without the appropriate privileges.
(CVE-2016-7570)
A reflected cross-site scripting (XSS) vulnerability exists due to a failure to validate input when handling HTTP exception messages before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user’s browser session. (CVE-2016-7571)
A flaw exists in the system.temporary route due to a failure to check ‘Export configuration’ permissions. An authenticated, remote attacker can exploit this to bypass intended access restrictions and download the full config export, resulting in the disclosure of sensitive information. (CVE-2016-7572)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
