Cross-site scripting (XSS) vulnerability in Drupal 8.x before 8.1.10 allows remote attackers to inject arbitrary web script or HTML via vectors involving an HTTP exception.

According to its self-reported version number, the detected Drupal application is affected by multiple vulnerabilities :

 - A flaw exists that is due to the program allowing users who have rights to edit a node to set the visibility for comments on that node. This may allow an authenticated remote attacker to adjust a node's comment visibility preferences without the appropriate privileges. (CVE-2016-7570)

 - A flaw exists that allows a reflected cross-site scripting (XSS) attack. This flaw exists because the program does not validate input when handling HTTP exception messages before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2016-7571)

 - A flaw exists related to the 'system.temporary' route that may allow an authenticated remote attacker to download the full config export without the appropriate privileges. This may allow the attacker to gain unauthorized access to sensitive information. (CVE-2016-7572)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Drupal installed on the remote server is 8.1.x prior to 8.1.10, and is affected by the following vulnerabilities :

 - A flaw exists that is due to the program allowing users who have rights to edit a node to set the visibility for comments on that node. This may allow an authenticated remote attacker to adjust a node's comment visibility preferences without the appropriate privileges. (CVE-2016-7570)
 - A flaw exists that allows a reflected cross-site scripting (XSS) attack. This flaw exists because the program does not validate input when handling HTTP exception messages before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2016-7571)
 - A flaw exists related to the 'system.temporary' route that may allow an authenticated remote attacker to download the full config export without the appropriate privileges. This may allow the attacker to gain unauthorized access to sensitive information. (CVE-2016-7572)

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.
